How do the capabilities and architecture of Django with Django REST Framework differ from asynchronous web frameworks like FastAPI, AIOHTTP, and Tornado?

Django and Django REST Framework (DRF) are synchronous web frameworks focused on rapid development of full-featured web applications and APIs with rich built-in functionality (ORM, authentication, admin panel, etc.).

Asynchronous frameworks like FastAPI, AIOHTTP, and Tornado are built on async/await and are aimed at high performance and scalability when handling a large number of concurrent requests.

Main differences:

• Architecture: Django is synchronous, based on WSGI; FastAPI, AIOHTTP, Tornado are asynchronous, using ASGI or their own event loops.
• Performance: Asynchronous frameworks are better suited for I/O-bound tasks and a large number of concurrent connections.
• Functionality: Django provides many ready-made components (ORM, templates, admin panel), DRF offers powerful tools for building APIs. FastAPI and others are more minimalist, requiring the selection and integration of third-party libraries.
• Development: Django is oriented towards the traditional MVC model, FastAPI uses a declarative style with Python type annotations.

Example of FastAPI:

from fastapi import FastAPI

app = FastAPI()

@app.get("/items/{item_id}")
async def read_item(item_id: int):
    return {"item_id": item_id}

Thus, the choice depends on the performance requirements, architecture, and functionality of the project.
