python-aiohttpHow to create a server with Python Aiohttp?

Creating a server with Python Aiohttp is easy and straightforward.

from aiohttp import web

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

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

web.run_app(app)

5. return web.Response(text=text) returns the greeting string as a response.
6. app = web.Application() creates an application instance.
7. app.add_routes([web.get('/', handle), web.get('/{name}', handle)]) adds routes to the application.
