Iteration using range() in Python - Mini Project: Build & Apply

Iteration using range()

📖 Scenario: You are helping a small bakery count the number of cupcakes they have baked each day for a week. They want to print the day numbers from 1 to 7 to keep track.

🎯 Goal: Build a simple program that uses range() to iterate through the days of the week (1 to 7) and print each day number.

📋 What You'll Learn

Create a variable to hold the total number of days (7)

Use range() to generate numbers from 1 to 7

Use a for loop with variable day to iterate over the range

Print each day number inside the loop

💡 Why This Matters

🌍 Real World

Counting days or items is common in many jobs, like tracking sales, attendance, or production.

💼 Career

Understanding how to use <code>range()</code> and loops helps automate repetitive tasks and process lists of data efficiently.

1

Set the total number of days

Create a variable called total_days and set it to 7.

Python

# Create a variable called total_days and set it to 7
# Your code here

Need a hint?

Use the equals sign = to assign the number 7 to total_days.

2

Create a range of days

Create a variable called days and set it to range(1, total_days + 1) to generate numbers from 1 to 7.

Python

total_days = 7
# Create a variable called days using range(1, total_days + 1)
# Your code here

Need a hint?

Remember that range() stops before the last number, so add 1 to total_days.

3

Use a for loop to iterate over days

Use a for loop with variable day to iterate over days.

Python

total_days = 7
days = range(1, total_days + 1)
# Use a for loop with variable day to iterate over days
# Your code here

Need a hint?

Write for day in days: and indent the next lines inside the loop.

4

Print each day number

Inside the for loop, write print(day) to display each day number.

Python

total_days = 7
days = range(1, total_days + 1)
for day in days:
    # Print the current day number
    # Your code here

Need a hint?

Use print(day) inside the loop to show each day number on its own line.
