Lists
Lists are one of the most commonly used data structures in Python. A list is an ordered collection of elements, which can be of any type, such as integers, floats, strings, or other objects. Lists are created using square brackets [] and elements are separated by commas.
# Creating a list of integers my_list = [1, 2, 3, 4, 5] # Creating a list of strings my_strings = ["apple", "banana", "cherry"]
Lists are mutable, which means their elements can be changed. Elements can be accessed using their index, starting from 0 for the first element.
# Accessing elements of a list print(my_list[0]) # Output: 1 print(my_strings[2]) # Output: "cherry" # Modifying elements of a list my_list[0] = 0 print(my_list) # Output: [0, 2, 3, 4, 5]
Lists are often used for data processing tasks such as sorting, filtering, and aggregation.
