asyncio is relative new library for asynchronous network programming.
On training session newcomers will learn how to:
develop asyncio-based WEB applications with help of aiohttp library and siblings
write tests for asynchronous code
make tiny but revealing asyncio library which shows all design concepts required for making good product for asyncio code
A lot of tips and tricks will be explained. Development for asyncio is really easy (much easier than Tornado and Twisted coding) but requires to change you mind a bit.
