Awaiting for Godot

Python 3.5 was released to the world on September 13, 2015. Included in this release was a substantial upgrade to asynchronous I/O support in the asyncio module, including brand new syntax in the Python language itself. In this article, we dive into modern asyncio and take it for a test drive on code involving low-level socket programming, high-level sockets, HTTP clients, and HTTP servers. Prepare yourself for the unexpected—this is not the Python you know. Just to be clear, you’ll need Python 3.5 or newer to try the examples.
