Comparison operators in Python - Mini Project: Build & Apply

Comparison Operators in Python

📖 Scenario: You are helping a store manager check if products meet certain price conditions to decide discounts.

🎯 Goal: Build a small program that compares product prices to a threshold and shows if they are expensive or affordable.

📋 What You'll Learn

Create a dictionary with product names and their prices

Create a price threshold variable

Use comparison operators to check if each product price is greater than the threshold

Print the product name and whether it is 'Expensive' or 'Affordable'

💡 Why This Matters

🌍 Real World

Stores often need to compare prices to decide discounts or promotions.

💼 Career

Understanding comparison operators is essential for data filtering and decision-making in programming jobs.

1

Create the product prices dictionary

Create a dictionary called products with these exact entries: 'Laptop': 1200, 'Smartphone': 800, 'Tablet': 400, 'Headphones': 150

Python

# Create the products dictionary with prices
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with keys and values separated by colons.

2

Set the price threshold

Create a variable called price_threshold and set it to 500

Python

products = {'Laptop': 1200, 'Smartphone': 800, 'Tablet': 400, 'Headphones': 150}
# Create the price_threshold variable
# Your code here

Need a hint?

Just assign the number 500 to the variable price_threshold.

3

Compare prices using comparison operators

Use a for loop with variables product and price to iterate over products.items(). Inside the loop, create a variable called status that is 'Expensive' if price > price_threshold, otherwise 'Affordable'

Python

products = {'Laptop': 1200, 'Smartphone': 800, 'Tablet': 400, 'Headphones': 150}
price_threshold = 500
# Use a for loop to check each product price
# Your code here

Need a hint?

Use a for loop to go through each product and its price. Use an if-else expression to set status.

4

Print the product status

Inside the for loop, write a print statement that shows the product name and its status in this format: "Laptop is Expensive"

Python

products = {'Laptop': 1200, 'Smartphone': 800, 'Tablet': 400, 'Headphones': 150}
price_threshold = 500
for product, price in products.items():
    status = 'Expensive' if price > price_threshold else 'Affordable'
    # Print the product and status
    # Your code here

Need a hint?

Use an f-string to combine product and status in the print statement.
