📚 Python Tutorial: Understanding Lists in Python

Introduction

Lists are one of Python’s most powerful data structures. They allow you to store multiple values in a single variable, making them essential for organizing and manipulating data.

1. Creating a List

fruits = ["apple", "banana", "cherry"]
print(fruits)

Try it yourself: Create a list of your favorite colors.

2. Accessing Elements

print(fruits[0])   # apple
print(fruits[2])   # cherry

Exercise: Print the second item in your list.

3. Modifying Lists

fruits[1] = "blueberry"
print(fruits)

Challenge: Replace one item in your list with a new value.

4. Adding and Removing Items

fruits.append("orange")
fruits.remove("apple")
print(fruits)

Try it: Add two new items and remove one.

5. Looping Through Lists

for fruit in fruits:
    print(fruit)

Exercise: Loop through your list and print each item with a custom message.

6. Real‑World Example: Shopping Cart

cart = ["milk", "bread", "eggs"]
cart.append("butter")
for item in cart:
    print("You bought:", item)

Challenge: Add a feature to remove an item from the cart.
