Understanding Python Lists

python lists tutorial

Python lists are one of the most versatile data types in the language. They are mutable, meaning you can change their content after creation. A list can store elements of different data types, including integers, strings, and even other lists.

For example:

my_list = [1, "hello", [3, 4, 5]]

You can access list elements using indexing like this:

first_element = my_list[0]

Lists also support various methods like append(), remove(), and sort() to manipulate the elements. These methods allow you to modify lists after they are created.

List Comprehensions

Python provides a feature called list comprehensions that allows for creating lists in a concise way:

squared_numbers = [x**2 for x in range(10)]

List comprehensions offer a more compact and readable way to generate lists, compared to using loops.
