Introduction

REST APIs are a fundamental part of web development, enabling communication between different services and applications. In this article, we'll explore how to create a simple REST API using Python, covering the basics and some common pitfalls.

Creating a Simple REST API

Let's start by creating a basic REST API in Python using the Flask framework. Flask is a micro web framework that can be used to create REST APIs easily.

First, install Flask if you haven't already:

pip install Flask

Enter fullscreen mode

Exit fullscreen mode

Now, let's create a simple API that responds with a greeting based on the HTTP method used.

# Import Flask library from flask import Flask , request , jsonify

# Create a Flask app app = Flask ( __name__ )

# Define a route for the root URL @app.route ( ' / ' , methods = [ ' GET ' , ' POST ' ]) def home (): # Handle GET requests if request . method == ' GET ' : return ' Welcome to the API! ' # Handle POST requests if request .…
