Asyncio is a relatively new feature in Python, with the async and await syntaxes only recently became proper keywords in Python 3.7. Asyncio allows you to write asynchronous programs in Python. In this tutorial, we’ll introduce you to an asyncio web library called aiohttp.

aiohttp is a library for building web client and server using Python and asyncio. We’ll introduce you to several key features of aiohttp; including routing, session handling, templating, using middlewares, connecting to database, and making HTTP GET/POST requests. We’ll provide best practises in building your aiohttp application, as well as how to write tests for your application.

We’ll use all new Python 3.7 features to build web services with asyncio and aiohttp.
