zip() function in Python - Mini Project: Build & Apply

Using the zip() function to combine lists

📖 Scenario: You work in a small shop and have two lists: one with product names and one with their prices. You want to pair each product with its price to see them together.

🎯 Goal: Learn how to use the zip() function to combine two lists into pairs.

📋 What You'll Learn

Create two lists with exact values

Create a variable to hold the zipped pairs

Use the zip() function correctly

Print the zipped pairs as a list

💡 Why This Matters

🌍 Real World

Combining related data from separate lists is common in shopping apps, inventory systems, and data analysis.

💼 Career

Understanding zip() helps in data processing tasks, making code cleaner and easier to read in many programming jobs.

1

Create two lists of products and prices

Create a list called products with these exact items: 'apple', 'banana', 'cherry'. Then create a list called prices with these exact numbers: 0.99, 0.5, 2.5.

Python

# Create the products list and the prices list
# Your code here

Need a hint?

Use square brackets [] to create lists and separate items with commas.

2

Create a variable to hold zipped pairs

Create a variable called product_price_pairs and set it to the result of zip(products, prices).

Python

products = ['apple', 'banana', 'cherry']
prices = [0.99, 0.5, 2.5]
# Create product_price_pairs using zip(products, prices)
# Your code here

Need a hint?

The zip() function takes two lists and pairs their items by position.

3

Convert zipped pairs to a list

Convert product_price_pairs to a list and store it in a variable called pairs_list.

Python

products = ['apple', 'banana', 'cherry']
prices = [0.99, 0.5, 2.5]
product_price_pairs = zip(products, prices)
# Convert product_price_pairs to a list called pairs_list
# Your code here

Need a hint?

Use the list() function to turn zipped pairs into a list you can see.

4

Print the list of product-price pairs

Print the variable pairs_list to display the combined product and price pairs.

Python

products = ['apple', 'banana', 'cherry']
prices = [0.99, 0.5, 2.5]
product_price_pairs = zip(products, prices)
pairs_list = list(product_price_pairs)
# Print pairs_list
# Your code here

Need a hint?

Use print(pairs_list) to show the final result.
