In Python, there are several popular frameworks available for developing REST APIs. Let’s discuss some of the most commonly used ones along with a brief description, a “Hello, World!” code example, and their pros and cons. Please note that the choice of framework depends on your specific requirements and preferences.

1. Flask:

Flask is a lightweight and flexible microframework that is easy to get started with. It provides a simple and intuitive API for building RESTful applications.

from flask import Flask

app = Flask(__name__)

def hello_world():
return 'Hello, World!'

if __name__ == '__main__':

– Minimalistic and easy to learn.
– Great for small to medium-sized applications.
– Good for rapid prototyping.
– Extensive documentation and a large community.

– Lacks some advanced features and scalability options.

2. Django:

Django is a full-featured web framework that includes built-in support for building APIs. It provides a powerful ORM, authentication, and various tools for rapid development.

from django.http import HttpResponse
from django.urls import path
from django.views.decorators.csrf import csrf_exempt

def hello_world(request):
return HttpResponse("Hello, World!")

urlpatterns = [
path('', hello_world),

– Comprehensive and follows the “batteries included” philosophy.
– Excellent for large-scale applications and complex use cases.
– Offers robust security features and extensive libraries.
– Provides excellent documentation and a mature ecosystem.

– Can be complex for simple applications.
– Might introduce some overhead due to its comprehensive nature.

3. FastAPI:

FastAPI is a modern, high-performance framework specifically designed for building APIs with Python. It is built on top of Starlette and provides automatic data validation, serialization, and interactive documentation.

from fastapi import FastAPI

app = FastAPI()

def hello_world():
return {"message": "Hello, World!"}

– High performance and scalability.
– Automatic generation of interactive API documentation.
– Easy integration with async frameworks.
– Type hinting and automatic data validation.

– Requires Python 3.7 or higher.
– Smaller community compared to Flask and Django.

Where each fit?

Each of these frameworks is suitable for different scenarios:

– Use Flask if you need a lightweight framework for small to medium-sized applications or quick prototypes.
– Choose Django if you require a comprehensive framework with extensive features, security, and scalability for large-scale applications.
– Opt for FastAPI if you prioritize performance, scalability, and automatic documentation generation, especially for modern APIs and microservices.

Consider your project requirements, performance needs, and development preferences to make an informed decision.
