Number Classification API

This is a DevOps/Backend guide to building a simple API that classifies numbers and returns fun mathematical facts about those numbers. The API checks the following —

1. Checks if a number is prime, perfect, or an Armstrong number.
2. Returns whether a number is odd or even.
3. Fetches a fun fact from NumbersAPI.

For this test we will need the following to help us complete the task.

1. A GitHub account
2. Render Account
3. Basic understanding of Python

Step 1 : Implementing a testing the code locally

1. Create a project folder for our api

mkdir flask-number-api
cd flask-number-api

2. Create the application files

— app.py – This will contain your Flask code.

— requirements.txt – List your dependencies.

In the app.py add the following block of code

#Importing Necessary Modules
#Flask: A web framework we will use to create the API.
#request: Retrieves the input number from the API request.
#jsonify: Converts Python dictionaries into JSON responses.
#CORS: Enables Cross-Origin Resource Sharing (CORS), allowing requests from different…
