How To Remove Tuple Brackets In Python

Round brackets are required in cases of ambiguity (if the tuple is part of a larger expression): Note that it is actually the comma which makes a tuple, not the parentheses. To create a tuple you use parenthesis instead of square brackets and just provide it the values separated by commas. Python sets are mutable. Arrays in Python is an altogether different thing. Tuples still keep track of every element individually like lists and strings, and thus allow for indexing and slicing to take place. See you tomorrow with a new topic in Python. Tuples are created by the comma operator, but they are not within square brackets. If you’re using Mac OS Leopard (10. 5 installed. A tuple with single item ends with a trailing comma. How to remove/delete a tuple in Python? Immutability of a tuple would again prevent you from deleting it in a Python program. In order to differentiate tuples from parenthesized expressions a trailing comma is required in the singleton tuple case. Next, passed the SQL delete query and data tuple to cursor. (len), which is a special internal method, implemented by most classes that have a length, that returns the array size. We can directly pass this list of tuples to the dictionary constructor. 0 questions, the first question has 1 answer and the second question has 2 answers. I can also use pop to remove an item at a particular index. However, by converting the tuple into a list, change the list, and convert the list back into a tuple. To Remove Character From String In Python, we can use string replace() or string translate() method. Python Lists. 0 questions, the first question has 1 answer and the second question has 2 answers. Tuples are immutable. It means you cannot change, append or delete the value of elements in tuple. A Computer Science portal for geeks. If duplicate items entered, it will be ignored and final set will always contain unique elements. Python sets are mutable. Python While Loop, Iteratiner the index is not recommended if we can iterate over the elements(as done in Method #1). update(red=1, blue=2). Tuples still keep track of every element individually like lists and strings, and thus allow for indexing and slicing to take place. This kind of problem can occur in data filtering applications. Tuple is similar with list, the main difference is list is mutable and tuple is immutable. 5 Functions versus Methods Most objects you create in Python will have a set of methods associated with them. • Python is widely used for scripting in Game menu applications effectively. The code tests the first item in an if-statement. insert(0, x),,,inserts at the front of the list, and a. Python ordereddict. How to remove brackets and commas from a list in python. A tuple can have any number of…. Convert a Python string to int type by using the int function. On the other hand, a Python tuple is immutable, so once it’s set up, it’s sort of “set in stone. join(new_zoo) it shows:. We can directly pass this list of tuples to the dictionary constructor. import collections. You can also pass a list of points instead of a tuple of points. Often I prefer to load my CSV file as a list of named tuples. tuple_A = (item 1, item 2, item 3,…, item n) Empty and One Single Item Tuple. In Python, tuples are similar to lists and are declared by parenthesis/round brackets. index() method searches an element in a tuple. Because you are not allowed to change the contents of a tuple, you can store data in one and that data can not be modified (accidentally or otherwise) by any code in your program. Python does not allow to modify a tuple after it is created. This searches the list by value (unlike del). In this post, we will talk about Python list functions and how to create, add elements, append, reverse, and many other Python list functions. For this when we need to print whole list without accessing the elements for loops, we require a method to perform this. In this article we will discuss how to Append, Insert, Replace and Delete elements from a tuple in python. Visual Studio Intellicode. Here is a short example showing a tuple definition, indexing, and slicing: >>>. The differences between tuples and lists are, the tuples cannot be changed unlike lists and tuples use parentheses, whereas lists use square brackets. To create a tuple in Python, place all the elements in a parenthesis, separated by commas. Here is a tuple: mytuple = (10, 20, 30) The difference with lists in terms of syntax is that tuples are written with round brackets. #!/usr/bin/python3 # -*- coding: UTF-8 -*- tuple1 = ('Google', 'Baidu', 'Apple')….

Funny though, the necessities and implications of list in Python is huge. you cannot change its content once created) and can hold mix data types. Python has a versatile component list. ) or tuples: lst = [] #empty list dic = {} #empty. Python lists have a built-in sort() method that modifies the list in-place and a sorted() built-in function that builds a new sorted list from an iterable. Create a Tuple: fruits = (“apple”, “banana”, “cherry”) print (fruits) Operations on Tuples. The only difference is that tuples can't be changed ie. A mutable object is one that can be changed. Tuples are sequences, just like lists. Similarly, you may use the join Python method with the set. It is an immutable, or unchangeable, ordered sequence of elements. ` from a sub-string enclosed in square brackets c# ,. A tuple list or list of tuples is simply a set of tuples (parentheses) enclosed within the list (square brackets). They also have different methods. (len), which is a special internal method, implemented by most classes that have a length, that returns the array size. Its functionality is similar to how an array works in other languages. The main difference between tuples and lists is that lists are mutable and tuples are not. Similar to List tuple are also used to group data of same or different data types but they immutable ordered sequence of items, i. A tuple looks like this: ('blue coral', 'staghorn coral', 'pillar coral'). Where as tuple can not be changed. A Python list is mutable – so you can add, remove and change items in it. Data Structure #2: Tuples in Python. Ugly, but effective. So far, we have shown examples of lists (list type), but slices can be used with other sequence objects such as strings str and tuples tuple as well. >>> countries = ('Vietnam', 'America', 'Germany', 'France', 'Canada') >>> first_eleven_fibonacci_number = (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89). SIPB maintains a python locker that has the current version of Python. They are just similar to lists but we can change the elements of the list once assigned. When it comes to data management in Python, you have to begin by creating a data frame. The data are currently in the form of a list of lists. On the other hand, the other important Python data structure, tuples, is the same as lists only immutable. If we attempt to reassign any element within a Tuple we will get a Type. Enclosing parentheses are optional in tuples. Similarly, you may use the join Python method with the set. class tuple ([iterable]) ¶. first even if the row name was first. Python sets are mutable. A tuple is an immutable ordered list of objects. Lists are much more popular though. Since modules are also objects in Python, the attributes of modules can be retrieved just like any attribute in an object. Try to remove an element. And so this is useful with append to simulate a stack. The output of this loop is: 0 a 1 b 2 c. A special problem is the construction of tuples containing 0 or 1 items: the syntax has some extra quirks to accommodate these. See the example below with the single tuple variable. The Python’s del keyword can make you delete a tuple. Tuples are immutable.

Define a unique name for the function and in parenthesis, you can specify your parameters. Negative indices count from the end of the tuple, just like a list. It is also possible to delete items using del statement by specifying a position or range with an index or slice. Give the name of the list, followed by the word remove with the value of the item you want to remove in parentheses. Similarly you cannot add or remove values either. Tuples can be used as values in sets whereas lists can not. However, there's an important difference between the two. lists and tuples can take any type of elements. We cannot insert or delete items in tuples with our programs. import collections. In this post, we will talk about Python list functions and how to create, add elements, append, reverse, and many other Python list functions. So, here is what I want the output to be without quotes and brackets. This was a deliberate design decision, and can best be explained by first understanding how Python dictionaries work. Similar to List tuple are also used to group data of same or different data types but they immutable ordered sequence of items, i. ("Badly formatted string (missing brackets).

Tuple can be dictionary Keys wheres List cannot be. join(LIST)) If the elements in the list aren't strings, you can convert them to string using either repr (if you want quotes around strings) or str (if you don't), like so:. Tuples are sequences, just like lists. A tuple can be used inside of an if-statement condition to replace (and optimize) a group of if-else branches. One-element tuples look like: 1, The essential element here is the trailing comma. Here, type-casting comes into the picture. The difference between list and tuple is that list are declared in square brackets and can be changed while tuple is declared in parentheses and cannot be changed. In Python tuples are written with round brackets. pop() vs comprehension; Python : How to create a list of all the Values in a dictionary ? Python: 4 ways to print items of a dictionary line by line.

Here is an example of a tuple in Python. But sometimes we want to modify the existing tuple, in that case we need to create a new tuple with updated elements only from the existing tuple. Execution time is less in case of tuple 4. The function takes a single argument which is the tuple variable. The init function runs (using the parameters you gave it in brackets) and then spits out an instance of that class, which in this case is assigned to the name "rectangle". A tuple is defined using parenthesis (and ) instead of [and ] that a list uses. Slices can also be applied on third-party objects like NumPy arrays, as well as Pandas series and data frames. It can define using different numbers of item like int, float, etc. In Python tuple sometimes elements or objects are repeated, these repeated elements and objects are duplicate elements in Python tuple. Version 2: Here we create a tuple (not a namedtuple). The differences between tuples and lists are, the tuples cannot be changed unlike lists and tuples use parentheses, whereas lists use square brackets. Method #3: Using while loop. join method but how to deal with tuple I want output to b. list, tuple, range. This recipe shows how to do a batch conversion of the content of multiple text files into a single PDF file, with a) an automatic page break after the content of each text file (in the PDF output), b) page numbering, and c) a header and footer on each page. So a tuple can contain elements that are integers, floats, strings, and so on. Python strongly encourages community involvement in improving the software. To randomly shuffle elements of lists (list), strings (str) and tuples (tuple) in Python, use the random module. In the following example, we initialize a tuple with all integers and convert it to a list using list(sequence). Tuples are safe. From your code it seems that the function computeGrade() returns this tuple, but this function is not shown in your code, neither is getLastname() or getFirstname(). x a generator is used whilst in Python 2. Write a Python program to remove an item from a tuple. The endswith() method returns True if a string ends with the specified suffix.

For further explanation on tuple, see Data Structure/Tuples. Tuples are identical to lists in all respects, except for the following properties: Tuples are defined by enclosing the elements in parentheses (()) instead of square brackets ([]). You will often find that there are several ways to perform a similar action in Python (and any other programming language for that matter). Lists and Tuples are used to store one or more Python objects or data-types sequentially. Tuple in Python is created using small brackets with the items in the tuple be separated by a comma (,). A tuple is an immutable ordered list of objects. To make a list you do: x = [0, 1] Python puts values in memory and then it creates labels to it. Visual Studio Intellicode. To convert a tuple to list we need to use list() method with given tuple as a parameter. • If it’s a dictionary you are after – use curly brackets. The problem with dictionaries in Python, is that they cannot be access (unlike JavaScript) via the dot notation.

Create a Tuple: fruits = (“apple”, “banana”, “cherry”) print (fruits) Operations on Tuples. As you can see we can use del following by dictionary name and in square brackets we can specify the key to delete the specified key value pair from dictionary. If you’re using Athena, your machine has Python, but it’s an old version. `enumerate` associates the original sequence elements with an arbitrarily chosen starting point and returns an iterator. #python; #tuple; How to get the length of a list or tuple or array in Python # Let me clarify something at the beginning, by array, you probably mean list in Python. Type-Casting In Python: The conversion of one data type into another data type is known as Type-casting. Once you try to set one of the tuple variables, you will get an exception. Here we will discuss the difference between Sets and List in Python. [] can't be used to access elements of number , because number is not subscript able. The code tests the first item in an if-statement. Python Docstring Generator. The sets do not support indexing. Well, most other ways aren't "wrong", they're just not the Python way of doing things. It's because tuples and strings are immutables; objects that can't be changed after its creation. Tuples indices are zero-based, just like a list, so the first element of a non-empty tuple is always t[0]. A common tuple use is the swapping of numbers:. Creating a tuple. Integers are an immutable type. Python while loop: Python while loop, nested while loop and infinite while loop examples.

When we create a new container variable, Python provides us with a quick way of defi ning which kind we require by the bracket choice: • If you want a tuple – wrap it in round brackets. A tuple is a sequence of immutable Python objects. The tuple elements are paired within the list with two element pairs. 7 version: # update-alternatives --remove python /usr/bin/python2. Tuples use parentheses, and lists use square brackets. But you can loop through the set items using a for loop, or ask if a specified value is present in a set, by using the in keyword. The “del” operator does deletions. You will often find that there are several ways to perform a similar action in Python (and any other programming language for that matter). Tuples are sequences, just like lists. If keyword arguments are specified, the dictionary is then updated with those key/value pairs: d. This is done to enable Python to differentiate between the tuple and the parentheses surrounding the object in the equation. Tuples are faster than lists. A tuple can be used inside of an if-statement condition to replace (and optimize) a group of if-else branches. Second, and more important, tuples are immutable. You can access tuple items by referring to the index number, inside square brackets: Negative indexing means beginning from the end, -1 refers to the last item, -2 refers to the second last item etc. you cannot change its content once created) and can hold mix data types. It can define using different numbers of item like int, float, etc. 2]] flattened = [val for sublist in list. Listing 1 shows the beginning of a Python script that: Packs a two-item tuple by applying the repeat operator to a single-item. This makes programs considerably longer and wastes valuable screen space, making it harder to get a good overview of a program. Creating a tuple is as simple as putting different comma-separated values. How to remove tuple brackets in python. Once you define a list you can add new items to them, remove existing items and so on, but you cannot do that with a tuple. Labels: Python. In simple words ,Nested list means List inside a list.

You can use this function from the python documentation in itertools reciepe to flatten the list. Python Forums on Bytes. I hope it helps you in your learning journey as it is doing wonders for me: Bracket Pair Colorizer. for x in range(1, 11): for y in range(1, 11): print('%d * %d = %d' % (x, y, x*y)) Early exits ; Like the while loop, the for loop can be made to exit before the given object is finished. Yes, there can be lists inside a list also. And so this is useful with append to simulate a stack. Slices can also be applied on third-party objects like NumPy arrays, as well as Pandas series and data frames. Previous: Write a Python program to find the length of a tuple. Regex to remove `. I need help with these python 3. RE : How to combine two lists to get the following desired result containing tuples? By Deshawncoradiana - 7 hours ago. Similar to how we used list before, you can also create a tuple via tuple(1,2,3). For instance, you can convert the list to a string and then remove the first and last characters: l = ['a', 2, 'c'] print str(l)[1:-1] 'a', 2, 'c'. You can remove it by value: your_list. Tuples are immutable sequences, typically used to store collections of heterogeneous data (such as the 2-tuples produced by the enumerate() built-in). How to remove tuple brackets in python. Example: x = [1,3,5,6,2,1,6] print(x) : Prints the complete list. With this, we come to an end of Python Data Structures Basic Cheat sheet. A tuple is represented by parentheses and commas, rather than the square brackets used by arrays. In the simplest case, it can remove the definition of a variable, as if that variable had not been defined. Here is a short example showing a tuple definition, indexing, and slicing: >>>. Negative indices count from the end of the tuple. Here, type-casting comes into the picture. A tuple can have any number of…. Python ordereddict. In Python programming, a list is created by placing all the items (elements) inside square brackets [], separated by commas. Once you define a list you can add new items to them, remove existing items and so on, but you cannot do that with a tuple. However, you can find the length of any Python variable by using this function. > print "%s, %s" % tuple(map(transform, pair)) Yes, it works. [] can't be used to access elements of number , because number is not subscript able. What is Tuple? A tuple is a collection which is ordered and unchangeable. The Python string data type is a sequence made up of one or more individual characters consisting of letters, numbers, whitespace characters, or symbols. Tuples variables are created by specifying a variable name, and the elements of the tuple should then be enclosed in a standard set of brackets/parentheses, with each element being separated with a comma. print is (correctly) printing the tuple that is returned from d. See full list on guru99. Sometimes, while working with Python tuples, we can have a problem in which we need to perform the removal of all the tuples which contain punctuation in tuples. The parentheses are optional, however, it is a good practice to use them. For example in our earlier example we could not do data[0]. Round bracket and Square bracket 2. 🙂 How NOT to Check if a List, Tuple, or Dictionary is Empty "So what if I want to use a different way to check if these structures are empty?", you say. I intend to parse a csv file with a format like 3520005,"Toronto (Ont. The list() method is used to convert tuples into list. remove(('Alba', 'Texas')) But keep in mind that it does not remove all occurrences of your element. 0 questions, the first question has 1 answer and the second question has 2 answers. Python has an amazing feature just for that called slicing. Lists in Python are simply an array. Python has a number of built-in functions that you may be familiar with, including: print() which will print an object to the terminal; int() which will convert a string or number data type to an integer data type; len() which returns the length of an object; Function names include parentheses and may include parameters. Syntax: del () Input Parameters: tuple_variable_name : where tuple is a tuple variable which we need to delete it. Creating Tuple. How to declare / initialize a tuple. You can access a list item within a tuple by referring to the list's index within the tuple, followed by the list item's index within the list (each index surrounded by its own set of square brackets). Tuples are unchangeable or immutable as it also is called. Flatten the list to "remove the brackets"using a nested list comprehension. Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses). The non-greedy version of the curly brackets, which matches the shortest string possible, has the closing curly bracket followed by a question mark. join(LIST)) If the elements in the list aren't strings, you can convert them to string using either repr (if you want quotes around strings) or str (if you don't), like so:. The brackets are optional when not ambiguous, but best to always use them. In this tutorial, we will learn the important difference between the list and tuples and how both are playing a significant role in Python. Python provides a range of constructs to deal with items. The parentheses are optional, however, it is a good practice to use them. Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Check the table given below. Problem: We are given a tuple and is asked to convert it into a list in python. To randomly shuffle elements of lists (list), strings (str) and tuples (tuple) in Python, use the random module. split() d = {}. , removing the quotes and bracket. the elements of the tuple can be enclosed in a list and thus will follow the characteristics in a similar manner as of a Python list. If we really want to update a tuple, we can use that tuple to create another tuple. One-element tuples look like: 1, The essential element here is the trailing comma. The differences between tuples and lists are, the tuples cannot be changed unlike lists and tuples use parentheses, whereas lists use square brackets. Python Tuple. When you're starting out like me learning Python, these are the 13 recommended extensions that I currently have installed. Still, if any confusion in Python Slice, ask freely in the comments. In Python, these are heavily used whenever someone has a list of lists - an iterable object within an iterable object. To convert a tuple to list we need to use list() method with given tuple as a parameter. Tuples are pretty easy to make. In Python tuples are written with round brackets. A tuple with a single item can be expressed as. We'll see two ways of initializing dictionary by solving word frequency problem. Lists are much more popular though. 5 installed. Then, the join method is used with the “ , “ separator i. Similar is the data frame in Python, which is labeled as two-dimensional data structures having different types of columns. The list is a similar element as that or array in other programming languages. Once you defined a tuple with parentheses (), you can not change its element. Python is a high-level, structured, open-source programming language that can be used for a wide variety of programming tasks. Conclusion. (The square brackets around the i in the method signature denote that the parameter is optional, not that you should type square brackets at that position. Getting the connected user's ip in python 4 'write' attribute using 'a+' 2 ; Reading or writing a double into a bin file 2 ; How to compare two files and save difference in thrid file 4 ; Python - Using a text file to feed into a python dictionary 3 ; Testing Divisibility 5 ; Converting a HTML file to a PNG file through Python script 6. In Python, tuples are immutable i. Python Lists; Python Dictionary ; In Python, a tuple is a comma-separated sequence of values. A tuple is a sequence of Python objects. Unpacking a Tuple in Python. Slicing doesn't change the original tuple, it just create a new tuple. first even if the row name was first. Access a List Item within a Tuple. A python sequence can hold any combination of objects. Creating Tuples. In Python we can remove elements from a set by using the discard and remove functions. Not a member of Pastebin yet? Sign Up, it unlocks many cool features!. This is a proposal to add two new methods, removeprefix() and removesuffix(), to the APIs of Python's various string objects. Python lists have a built-in sort() method that modifies the list in-place and a sorted() built-in function that builds a new sorted list from an iterable. Python Server Side Programming Programming. Give the name of the list, followed by the word remove with the value of the item you want to remove in parentheses. Provide details and share your research! But avoid …. The ease with which you can perform this task is almost scary because it’s too easy. Version 1: We test an if that checks a variable against a tuple of 3 values. And Python never creates a new list if you assign a list to a variable. But you do worry about mutable vs immutable data. The square brackets signal that a list has been returned from the original tuple value that was passed through the list() method. First, let’s look at what a Python tuple is and then we will discuss how to create, access, slice, delete tuple in Python. access tuples python slice. Pretty much in every project, you need to write a code to check if the list has any duplicates, and if it has copies, then we need to remove them and return the new list with the unique items. Write a python program to remove repeated elements from a given list without using built-in methods. To randomly shuffle elements of lists (list), strings (str) and tuples (tuple) in Python, use the random module. It's one of the robust, feature-rich online compilers for python language, supporting both the versions which are Python 3 and Python 2. Here is an example of a tuple in Python. However, by converting the tuple into a list, change the list, and convert the list back into a tuple. 3? List<> Capacity returns more items than added. Once Python has created a tuple in memory, it cannot be changed. The bracket means there is a tuple in that position of the list. Tuples are immutable. >>> a = (1, 2) >>> b = (4, 5) >>> t = (a, b) >>> t ((1, 2), (4, 5)) However, now that tuples are not mutable, we cannot update the tuple inside a tuple either. The set is created by using the curly braces and items are separated by a comma. Often I prefer to load my CSV file as a list of named tuples. What if a tuple has mutable objects as elements? Here, comes the surprise. There is, of course, nothing wrong. Tuples are easy to create by simply adding elements in parentheses and separating them with commas. Q-55: What is a dictionary in Python programming? A dictionary is a data structure known as an associative array in Python which stores a collection of objects. Lists in Python are simply an array. Example: x = [1,3,5,6,2,1,6] print(x) : Prints the complete list. Labels: Python.

Quizlet flashcards, activities and games help you improve your grades. A tuple is collection that cannot be modified. Round brackets are required in cases of ambiguity (if the tuple is part of a larger expression): Note that it is actually the comma which makes a tuple, not the parentheses. In this article we will discuss how to Append, Insert, Replace and Delete elements from a tuple in python. Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses). It returns the sublist of data that goes from index 1 (inclusive) to index 2 (exclusive). list is the equivalent of arrays in JavaScript or PHP. Insert the reference into your code to access the array’s size. One-element tuples look like: 1, The essential element here is the trailing comma. Since, Python Tuples utilize less amount of space, creating a list of tuples would be more useful in every aspect. my_tuple = (1, 2, 3) # Error: 'tuple' object doesn't support item deletion del my_tuple[1]. Round bracket and Square bracket 2. A Computer Science portal for geeks. This recipe shows how to do a batch conversion of the content of multiple text files into a single PDF file, with a) an automatic page break after the content of each text file (in the PDF output), b) page numbering, and c) a header and footer on each page. Slicing can not only be used for lists, tuples or arrays, but custom data structures as well, with the slice object, which will be used later on in this article. To make the code more readable, we can remove one of the pairs of parentheses by using a variable:. Creating a tuple. Python is amazing. 1-1 tuple basics. How to write comments in python? Use ‘#’ for single-line comments For multi-line, you can use three quotes Figure 1: Comments in python For multi-line comments, you can select all the lines that you want to comment on and then use ‘ctrl + /’ (‘command + /’ for mac) to comment on all the lines.

It works exactly the same as with a list, with the # exception that the key is no longer an integer. 🙂 How NOT to Check if a List, Tuple, or Dictionary is Empty "So what if I want to use a different way to check if these structures are empty?", you say. Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Tuples are sequences, just like lists. Tuples are safe. > but it feels a bit hackish to me. 36 Tuples: A tuple is a sequence of immutable Python objects. However, an empty tuple must use an enclosing parenthesis. associative arrays, hash maps, etc. Once you defined a tuple with parentheses (), you can not change its element. Python tuples are slightly faster than Python lists with the same calculations. I recommend using Python 2. They're for string t. It has no commas or > parentheses. Similarly you cannot add or remove values either. As a result, they cannot be modified or changed throughout the program. The code tests the first item in an if-statement. But the differences between a tuple and a list is that tuples can not be changed like we can change an item of a list. VenkataSubramanian provided a nice summary of Python's tuple syntax [1]. insert(len(a), x) is equivalent to a. Like lists, all of the common sequence operations are available. Lists and Tuples are used to store one or more Python objects or data-types sequentially. The only difference is that tuples can’t be changed i. In Python, the string object is immutable and hence sometimes poses visible restrictions while coding the constructs that are required in day-day programming. VenkataSubramanian provided a nice summary of Python's tuple syntax [1]. Tuples are sequences, just like lists. Tuples are enclosed in parenthesis (), a tuple looks like:. Python Preview. 5), your computer already has Python 2. How to create a tuple in Python. Tuples are identical to lists in all respects, except for the following properties: Tuples are defined by enclosing the elements in parentheses (()) instead of square brackets ([]).
