Passing asyncio loop by argument or using default asyncio loop

Question

I\'m using asyncio in my application and i\'m a litte bit confused about passing the event loop as argument.

You\'ve three possibilities when writing a func

Answer 1

A good (as in praised by Guido van Rossum) blog post discussing this is Some thoughts on asynchronous API design in a post-async/await world. With a follow up discussion from python core developers here.

TLDR;

If you're only using one event loop, it doesn't matter.

If you're managing multiple loops, and have python >= 3.6 it mostly doesn't matter: Do not use argument and use asyncio.get_event_loop() where needed, it will give you the correct loop.
