Why loops are needed in Python - See It in Action

Why loops are needed

📖 Scenario: Imagine you have a list of fruits and you want to say hello to each fruit. Doing this one by one is slow and boring. Loops help us do this quickly and easily.

🎯 Goal: You will create a list of fruits, set up a counter, use a loop to greet each fruit, and then print all greetings.

📋 What You'll Learn

Create a list called fruits with these exact items: 'apple', 'banana', 'cherry'

Create a variable called greetings and set it to an empty list

Use a for loop with variable fruit to go through fruits

Inside the loop, add the string "Hello, {fruit}!" to greetings

Print the greetings list

💡 Why This Matters

🌍 Real World

Loops are used in many real tasks like sending emails to many people or checking items in a list.

💼 Career

Understanding loops is important for any programming job because they help automate repetitive work.

1

Create the list of fruits

Create a list called fruits with these exact items: 'apple', 'banana', 'cherry'

Python

# Create the list called fruits with 'apple', 'banana', 'cherry'
# Your code here

Need a hint?

Use square brackets [] to make a list and separate items with commas.

2

Create an empty greetings list

Create a variable called greetings and set it to an empty list []

Python

fruits = ['apple', 'banana', 'cherry']
# Create an empty list called greetings
# Your code here

Need a hint?

An empty list is made with [].

3

Use a for loop to greet each fruit

Use a for loop with variable fruit to go through fruits. Inside the loop, add the string f"Hello, {fruit}!" to the greetings list using append()

Python

fruits = ['apple', 'banana', 'cherry']
greetings = []
# Use a for loop with fruit to go through fruits
# Inside the loop, add f"Hello, {fruit}!" to greetings
# Your code here

Need a hint?

Use for fruit in fruits: and inside the loop use greetings.append(f"Hello, {fruit}!").

4

Print the greetings list

Write print(greetings) to display the list of greetings

Python

fruits = ['apple', 'banana', 'cherry']
greetings = []
for fruit in fruits:
    greetings.append(f"Hello, {fruit}!")
# Print the greetings list
# Your code here

Need a hint?

Use print(greetings) to show the list.
