Page-based pagination in Rest API - Mini Project: Build & Apply

Page-based pagination

📖 Scenario: You are building a simple REST API that returns a list of products. Since the list can be very long, you want to show only a few products per page. This is called page-based pagination.Imagine a store website where customers can browse products page by page.

🎯 Goal: Create a REST API endpoint that returns products for a given page number and page size.You will build the data, set up pagination parameters, apply pagination logic, and finally output the paginated products.

📋 What You'll Learn

Create a list of products with exact names

Create variables for page number and page size

Use slicing to get the correct products for the current page

Print the paginated list of products

💡 Why This Matters

🌍 Real World

Page-based pagination is used in websites and apps to show large lists in smaller chunks, making it easier for users to browse.

💼 Career

Understanding pagination is important for backend developers building APIs and frontend developers displaying data efficiently.

1

Create the product list

Create a list called products with these exact strings: 'Apple', 'Banana', 'Carrot', 'Date', 'Eggplant', 'Fig', 'Grape', 'Honeydew'.

Rest API

# Create the list of products
# Your code here

Need a hint?

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

2

Set page number and page size

Create two variables: page_number set to 2 and page_size set to 3.

Rest API

products = ['Apple', 'Banana', 'Carrot', 'Date', 'Eggplant', 'Fig', 'Grape', 'Honeydew']
# Create page_number and page_size variables
# Your code here

Need a hint?

Assign the number 2 to page_number and 3 to page_size.

3

Calculate paginated products

Create a variable start_index that calculates the first product index for the current page using page_number and page_size. Then create end_index as start_index + page_size. Finally, create paginated_products by slicing products from start_index to end_index.

Rest API

products = ['Apple', 'Banana', 'Carrot', 'Date', 'Eggplant', 'Fig', 'Grape', 'Honeydew']
page_number = 2
page_size = 3
# Calculate start_index, end_index, and paginated_products
# Your code here

Need a hint?

Remember that list indexes start at 0, so page 1 starts at index 0.

4

Print the paginated products

Write a print statement to display the paginated_products list.

Rest API

products = ['Apple', 'Banana', 'Carrot', 'Date', 'Eggplant', 'Fig', 'Grape', 'Honeydew']
page_number = 2
page_size = 3
start_index = (page_number - 1) * page_size
end_index = start_index + page_size
paginated_products = products[start_index:end_index]
# Print the paginated_products list
# Your code here

Need a hint?

Use print(paginated_products) to show the products on page 2.
