python-aiohttpHow to use Python Aiohttp with Asyncio?

Python Aiohttp with Asyncio can be used to create asynchronous web applications. To use Aiohttp with Asyncio, first import the necessary modules:

import asyncio
from aiohttp import web

Then, create a function that will be used as a handler for the web application:

async def handle(request):
    name = request.match_info.get('name', "Anonymous")
    text = "Hello, " + name
    return web.Response(text=text)

The output of the above code will be "Hello, [name]".

Next, create an instance of the web application:

app = web.Application()
app.add_routes([web.get('/', handle),
                web.get('/{name}', handle)])

Finally, run the web application:

web.run_app(app)

The web application will now be running and can be accessed at http://localhost:8080.
