Episode 7: AsyncIO + Music, Origins of Black, and Managing Python Releases

The Real Python Podcast

May 01, 2020 1h 27m

Want to learn more about AsyncIO in Python, with an example where you can see and hear events being triggered in real-time? This week we have Łukasz Langa on the show. Łukasz has created a talk for PyCon 2020 online about using AsyncIO with Music.

In his talk he shows live examples of coroutines, gathering, the event loop and events being triggered to create a piece of music. We also talk about his role as the release manager for Python 3.8 and 3.9. Łukasz provides background on the origins of his very popular, uncompromising code formatter, Black, and the types of problems it can solve inside of an organization.

Łukasz previously worked for Facebook, which is where he started Black. He talks about recently moving back to Poland. We discuss his current work for Edge DB, building a new generation object-relational database.
