Asyncio without Asyncio a workshop with Yan Yanchii

Sunday 17 September 14:00 (3 hours)

Room 351

This tutorial aims to demystify asyncio builtin module by implementing it from scratch without any dependencies other than the Python Standard Library.

We will go through the problem of blocking IO and how it is possible to solve it without single “async” and “await” statement using native Python concepts. Then, we will demystify async/await syntax and see how it is implemented.

We will also build our own scheduler which will have a similar API as asyncio, which will be able to run async functions the same way asyncio does. And finally we will build real asynchronous http proxy using our own asyncio implementation.

Why reinvent the wheel? – “I hear and I forget. I see and I remember. I do and I understand”.

Yan Yanchii

I'm a senior software engineer at Kiwi.com, a leading global travel tech company headquartered in the Czech Republic, and I work on the Search team.

Originally from Ukraine, I speak six languages and have a strong passion for computer science and low-level programming. Despite my young age of 25, I've gained extensive experience and expertise in Python and C. I particularly enjoy delving into CPython and its internal workings. My preference for creating things from scratch, as opposed to relying on pre-made solutions, has helped me develop a profound grasp of the technical foundations of software development.

I'm thrilled to share my knowledge and enthusiasm for Python and low-level programming with the Python community.
