Creating dictionary from two sequences in Python - Try It Yourself

Creating dictionary from two sequences

📖 Scenario: You have two lists: one with product names and another with their prices. You want to combine them into a dictionary where each product name is a key and its price is the value.

🎯 Goal: Build a dictionary from two lists using Python, matching each product with its price.

📋 What You'll Learn

Create two lists named products and prices with exact values

Create a variable called product_price_dict to hold the dictionary

Use a Python method to combine products and prices into product_price_dict

Print the product_price_dict to show the final dictionary

💡 Why This Matters

🌍 Real World

Combining two related lists into a dictionary is common when working with data like product catalogs, student grades, or contact information.

💼 Career

This skill is useful for data processing, web development, and automation tasks where you need to organize paired data efficiently.

1

Create the product and price lists

Create a list called products with these exact values: 'apple', 'banana', 'cherry'. Also create a list called prices with these exact values: 0.99, 0.50, 2.00.

Python

# Create the lists products and prices with the exact values
# Your code here

Need a hint?

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

2

Prepare the dictionary variable

Create an empty dictionary called product_price_dict to store the combined product-price pairs.

Python

products = ['apple', 'banana', 'cherry']
prices = [0.99, 0.50, 2.00]

# Create an empty dictionary called product_price_dict
# Your code here

Need a hint?

Use curly braces {} to create an empty dictionary.

3

Combine the lists into a dictionary

Use the zip function with products and prices to create product_price_dict by converting the zipped pairs into a dictionary.

Python

products = ['apple', 'banana', 'cherry']
prices = [0.99, 0.50, 2.00]

product_price_dict = {}

# Use zip and dict to combine products and prices into product_price_dict
# Your code here

Need a hint?

The zip function pairs items from two lists. Then dict() converts those pairs into a dictionary.

4

Print the dictionary

Print the product_price_dict to display the combined dictionary of products and prices.

Python

products = ['apple', 'banana', 'cherry']
prices = [0.99, 0.50, 2.00]

product_price_dict = dict(zip(products, prices))

# Print the product_price_dict
# Your code here

Need a hint?

Use the print() function to show the dictionary on the screen.
