Data is an essential concept in today’s world. You consume data every second, whether you’re searching online or using your favorite app. This data has to be in the right format in order to make sense. In this tutorial, we will look at how to perform data filtering, sorting, and pagination in Python using the Flask Micro-framework.

What is Flask?

Flask is a micro-framework written in Python. It’s simple and easy to set up since it doesn’t require particular tools or libraries. It has no database abstraction layer, form validation, or other components. Flask aims to keep the core simple but extensible.

Create a Basic Flask Application

We will start by creating a movie API server. The API server will be able to perform the following :

• Retrieve records from the server based on search terms
• Pagination up to five records per page
• Sorting of movies based on the best ratings

Create a project directory and set up a virtual environment. You must have virtualenv installed. Virtual environments help to separate project dependencies.

Activate virtual environment.

Inside the Movie folder, create a file app.py.
