Python List

Python List:

In Python, a list is a collection of items that can hold values of different data types. Lists are one of the built-in data types in Python and are denoted by square brackets [ ].

Here’s an example of creating a list in Python:

python

Copy code

my_list = [1, 2, 3, 4, 5]

In the above example, my_list is a list that contains integers from 1 to 5. However, lists can also contain elements of different types, such as strings, floats, or even other lists. Here’s an example of a list with mixed data types:

python

Copy code

my_list = [1, “Hello”, 3.14, True]

Lists are mutable, which means you can modify them by adding, removing, or changing elements. You can access elements of a list using their index, which starts from 0 for the first element. Here’s an example:

python

Copy code

my_list = [1, 2, 3, 4, 5]

print(my_list[0])  # Output: 1

print(my_list[2])  # Output: 3

You can perform various operations on lists, such as appending or removing elements, checking the length, slicing, and more. Here are some common list operations:

python

Copy code

my_list = [1, 2, 3]

my_list.append(4)          # Adds an element at the end of the list

my_list.remove(2)          # Removes the element with the specified value

length = len(my_list)      # Returns the number of elements in the list

sub_list = my_list[1:3]    # Returns a new list with elements from index 1 to 2 (exclusive)

These are just a few examples of what you can do with lists in Python. Lists are a versatile and commonly used data structure that allows you to store and manipulate collections of items efficiently.
