Introduction to Lists

← Back to Course

Introduction to Lists

A variable usually stores a single value. But what if you need to store several values together, such as the names of students, a list of products, or your favorite colors?

This is where lists are useful.

A list is a collection of items stored in a single variable. Lists keep items in order, and each item has its own position called an index.

Creating a List

Create a list using square brackets [] and separate the items with commas.

colors = ["Red", "Blue", "Green"]

This list contains three items:

Red
Blue
Green

Accessing Items

Python uses zero-based indexing, which means the first item is at index 0, not 1.

print(colors[0])
print(colors[2])

Output

Red
Green

Here's how the indexes work:

Index:   0       1       2
        Red     Blue    Green
