Elif ladder execution in Python - Mini Project: Build & Apply

Elif Ladder Execution

📖 Scenario: You are creating a simple program to categorize a person's age group based on their age. This is useful in many real-life situations like ticket pricing, event access, or surveys.

🎯 Goal: Build a Python program that uses an elif ladder to print the correct age group for a given age.

📋 What You'll Learn

Create a variable called age with a specific integer value.

Create a variable called child_age_limit and set it to 12.

Use an if-elif-else ladder to check the age against child_age_limit and other age ranges.

Print the correct age group as a string: 'Child', 'Teenager', 'Adult', or 'Senior'.

💡 Why This Matters

🌍 Real World

Age group classification is used in ticket pricing, content restrictions, and marketing to target the right audience.

💼 Career

Understanding conditional statements like <code>elif</code> ladders is fundamental for programming jobs that involve decision-making logic.

1

Set the age variable

Create a variable called age and set it to 20.

Python

# Create a variable called age and set it to 20
# Your code here

Need a hint?

Use the assignment operator = to set the value.

2

Set the child age limit

Create a variable called child_age_limit and set it to 12.

Python

age = 20
# Create a variable called child_age_limit and set it to 12
# Your code here

Need a hint?

This variable will help us decide if someone is a child or older.

3

Write the elif ladder to check age groups

Write an if-elif-else ladder using the variables age and child_age_limit to print:
- 'Child' if age is less than or equal to child_age_limit
- 'Teenager' if age is between 13 and 19 inclusive
- 'Adult' if age is between 20 and 64 inclusive
- 'Senior' if age is 65 or older

Python

age = 20
child_age_limit = 12
# Write the if-elif-else ladder to check age groups
# Your code here

Need a hint?

Use comparison operators like <= and logical operators like and or chained comparisons.

4

Run the program to see the output

Run the program and observe the printed output for the given age.

Python

age = 20
child_age_limit = 12
if age <= child_age_limit:
    print('Child')
elif 13 <= age <= 19:
    print('Teenager')
elif 20 <= age <= 64:
    print('Adult')
else:
    print('Senior')
# Run the program to see the output

Need a hint?

The program should print the correct age group based on the value of age.
