What are some popular async libraries in Python?

Some popular async libraries in Python include asyncio, aiohttp, and FastAPI. Would you like to know more about any of these?

Can you explain how asyncio works?

Sure! asyncio is a library to write concurrent code using the async/await syntax. It allows you to run multiple tasks at the same time without blocking the main thread.

What about aiohttp? How is it different?

aiohttp is an asynchronous HTTP client/server framework. It allows you to make HTTP requests and build web servers using async features, making it great for web applications.

Can you give me an example of using FastAPI?

Absolutely! FastAPI is a modern web framework for building APIs with Python 3.6+ based on standard Python type hints. Here's a simple example:

from fastapi import FastAPI

app = FastAPI()

@app.get("/")
async def read_root():
    return {"Hello": "World"}
