Tuple unpacking in Python - Mini Project: Build & Apply

Tuple Unpacking with Product Data

📖 Scenario: You work in a store and have a list of products. Each product is stored as a tuple with its name, price, and quantity.

🎯 Goal: You will learn how to use tuple unpacking to easily get each piece of information from the product tuples.

📋 What You'll Learn

Create a list of product tuples with exact values

Create a variable to count total items in stock

Use tuple unpacking in a for loop to get product details

Print the total number of items in stock

💡 Why This Matters

🌍 Real World

Stores and warehouses often keep product data as tuples or lists. Tuple unpacking helps quickly access each piece of information.

💼 Career

Knowing tuple unpacking is useful for data processing tasks in jobs like inventory management, data analysis, and software development.

1

Create the product list

Create a list called products with these exact tuples: ("Apple", 0.5, 10), ("Banana", 0.3, 20), and ("Orange", 0.7, 15).

Python

# Create the list called products with the given tuples
# Your code here

Need a hint?

Use square brackets [] to create a list and parentheses () for each product tuple.

2

Create a total count variable

Create a variable called total_quantity and set it to 0 to hold the total number of items in stock.

Python

products = [("Apple", 0.5, 10), ("Banana", 0.3, 20), ("Orange", 0.7, 15)]
# Create total_quantity variable and set to 0
# Your code here

Need a hint?

Just write total_quantity = 0 on a new line.

3

Use tuple unpacking in a loop

Use a for loop with tuple unpacking to get name, price, and quantity from each product in products. Inside the loop, add quantity to total_quantity.

Python

products = [("Apple", 0.5, 10), ("Banana", 0.3, 20), ("Orange", 0.7, 15)]
total_quantity = 0
# Use a for loop with tuple unpacking to add quantities
# Your code here

Need a hint?

Write for name, price, quantity in products: and inside add quantity to total_quantity.

4

Print the total quantity

Write a print statement to display the text Total items in stock: followed by the value of total_quantity.

Python

products = [("Apple", 0.5, 10), ("Banana", 0.3, 20), ("Orange", 0.7, 15)]
total_quantity = 0
for name, price, quantity in products:
    total_quantity += quantity
# Print the total quantity below
# Your code here

Need a hint?

Use an f-string like print(f"Total items in stock: {total_quantity}").
