A list is a number of items in an ordered or unordered structure. A list can be used for a number of things like storing items or deleting and adding items. But for the programmer to perform the different tasks for the list, the program must have enough memory to keep up with changes done to the list.
What is a list in data?
A list is an ordered data structure with elements separated by a comma and enclosed within square brackets. For example, list1 and list2 shown below contains a single type of data. Here, list1 has integers while list2 has strings. Lists can also store mixed data types as shown in the list3 here.
What is list in computer science Python?
A list is a data structure in Python that is a mutable, or changeable, ordered sequence of elements. Each element or value that is inside of a list is called an item. Just as strings are defined as characters between quotes, lists are defined by having values between square brackets [ ].

How do you make a list in coding?
Making an unordered list has two steps: making the list and adding the list items. To make the unordered list, write the unordered list tags <ul> </ul> . Next, add your list items inside the unordered list tags. To make each list item, use the list item tags <li> </li> and write the list item inside the tags.
How do you create a list in Python?
In Python, a list is created by placing elements inside square brackets [] , separated by commas. A list can have any number of items and they may be of different types (integer, float, string, etc.). A list can also have another list as an item.

What is list in computer science class 9?
list is a data type that represents a countable number of ordered values.
What is a list in computer class 8?
Answer: In computer science, a list or sequence is an abstract data type that represents a countable number of ordered values, where the same value may occur more than once.
What is list 11 computer science?
List is a sequence like a string and a tuple except that list is mutable whereas string and tuple are immutable.
What is list in Python Class 11?
the python lists are containers that are used to store a list of values of any type. Unlike other variables python lists are mutable i.e., you can can change the elements of a list in place; python will not create a fresh list when you make changes to an element of a list.
What is a tuple Class 11?
A tuple is an ordered sequence of elements of different data types, such as integer, float, string, list or even a tuple. Elements of a tuple are enclosed in parenthesis (round brackets) and are separated by commas. Like list and string, elements of a tuple can be accessed using index values, starting from 0.
What do you mean by list Class 11?
Class 11 Computer Science List in Python Notes and Questions. 7.1 Introduction: List is a collection of elements which is ordered and changeable (mutable). Allows duplicate values. A list contains items separated by commas and enclosed within square brackets ([ ]).
How do you define a tuple?
Tuple. Tuples are used to store multiple items in a single variable. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and unchangeable.
What is a tuple vs array?
Tuples have a slight performance improvement to lists and can be used as indices to dictionaries. Arrays only store values of similar data types and are better at processing many values quickly.
What is a tuple vs list?
The key difference between the tuples and lists is that while the tuples are immutable objects the lists are mutable. This means that tuples cannot be changed while the lists can be modified. Tuples are more memory efficient than the lists.
What are lists and tuples?
In Python, list and tuple are a class of data structures that can store one or more objects or values. A list is used to store multiple items in one variable and can be created using square brackets. Similarly, tuples also can store multiple items in a single variable and can be declared using parentheses.
What is difference between Array and list?
List is used to collect items that usually consist of elements of multiple data types. An array is also a vital component that collects several items of the same data type. List cannot manage arithmetic operations. Array can manage arithmetic operations.
What is difference between set and list?
It is an ordered collection of objects in which duplicate values are allowed to store. List preserves the insertion order, it allows positional access and insertion of elements.
