Which Python frameworks have you used for backend development?

[fastqa]

I have used several Python frameworks for backend development, including FastAPI, Flask, and Django.

FastAPI

• FastAPI is known for its high performance and ease of use. It's built on top of Starlette and Pydantic, making it ideal for building APIs quickly with automatic validation and serialization.

Flask

• Flask is a lightweight and flexible framework. It's great for small to medium-sized applications and provides simplicity with its minimalistic design.

Django

• Django is a robust and comprehensive framework. It includes an ORM, authentication, and many other features out-of-the-box, making it suitable for large-scale applications.

Use Cases

• FastAPI: Real-time applications, microservices
• Flask: Prototyping, small web applications
• Django: Large web applications, complex projects

Example Code Snippet

from fastapi import FastAPI
app = FastAPI()
@app.get("/")
def read_root():
    return {"Hello": "World"}

Common Pitfalls

• FastAPI: Understanding async programming
• Flask: Managing extensions and dependencies
• Django: Handling migrations and ORM complexities
