Pagination with limit and offset in Rest API - Mini Project: Build & Apply

Pagination with limit and offset

📖 Scenario: You are building a simple REST API that returns a list of products. To avoid sending too many products at once, you want to add pagination using limit and offset parameters.

🎯 Goal: Create a REST API endpoint that returns a paginated list of products using limit and offset query parameters.

📋 What You'll Learn

Create a list called products with 10 product names.

Create variables limit and offset to control pagination.

Use limit and offset to slice the products list.

Print the paginated list of products.

💡 Why This Matters

🌍 Real World

Pagination is used in APIs to send data in small chunks so users can load pages quickly without waiting for all data at once.

💼 Career

Understanding pagination is important for backend developers and API designers to improve performance and user experience.

1

Create the product list

Create a list called products with these exact product names: 'Apple', 'Banana', 'Carrot', 'Dates', 'Eggplant', 'Fig', 'Grapes', 'Honeydew', 'Iceberg', 'Jackfruit'.

Rest API

# Create the list called products with the exact names
# Your code here

Need a hint?

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

2

Set limit and offset variables

Create two variables: limit set to 3 and offset set to 4.

Rest API

products = ['Apple', 'Banana', 'Carrot', 'Dates', 'Eggplant', 'Fig', 'Grapes', 'Honeydew', 'Iceberg', 'Jackfruit']
# Create limit and offset variables
# Your code here

Need a hint?

Use simple assignment like limit = 3 and offset = 4.

3

Slice the products list using limit and offset

Create a new list called paginated_products that contains products starting from offset and includes limit number of products using list slicing.

Rest API

products = ['Apple', 'Banana', 'Carrot', 'Dates', 'Eggplant', 'Fig', 'Grapes', 'Honeydew', 'Iceberg', 'Jackfruit']
limit = 3
offset = 4
# Create paginated_products using slicing
# Your code here

Need a hint?

Use products[offset:offset+limit] to get the slice.

4

Print the paginated products

Print the paginated_products list to show the paginated result.

Rest API

products = ['Apple', 'Banana', 'Carrot', 'Dates', 'Eggplant', 'Fig', 'Grapes', 'Honeydew', 'Iceberg', 'Jackfruit']
limit = 3
offset = 4
paginated_products = products[offset:offset+limit]
# Print the paginated_products list
# Your code here

Need a hint?

Use print(paginated_products) to display the list.
