Michael #1: async-timeout

• An asyncio-compatible timeout context manager.
• The context manager is useful in cases when you want to apply timeout logic around block of code or in cases when asyncio.wait_for() is not suitable.
• Not finished yet timeout can be rescheduled by shift_by() or shift_to() methods

Brian #2: PyPI Project URLs Cheatsheet

• Daniel Roy Greenfield
• There’s some cool icons available under “Project Links” on pypi.org project pages.
• How do you get those? And which ones are available.
• Daniel has found out where to look, and built us a cheat sheet. Nice.

Michael #3: httpx-sse

• Consume Server-Sent Event (SSE) messages with HTTPX.
• SSE are super lightweight, server → client only subscriptions.
• Like websockets but less overhead (especially for iot and mobile devices)
• httpx-sse provides the connect_sse and aconnect_sse helpers for connecting to an SSE endpoint.
• The resulting EventSource object exposes the .iter_sse() and .aiter_sse() methods to iterate over the server-sent events.

Brian #4: Creating a context manager in Python

• Trey Hunner
• Context managers are those things you use in a with block.
• There’s a bunch of cool built in ones.
• Building your own is a handy skill to have to clean up your code, and they’re pretty easy, with Trey’s tutorial.
• Shown is a great example of temporarily modifying an environmental variable.
• Then he gets into what you need to know about as, __enter__, and __exit__.

Extras

Brian:

• I think I’ll nix the intro music to Python People. I didn’t know what music to use, so I re-used the music from Test & Code. And I got some very honest feedback that it just doesn’t fit and was better without it. So I’ll rip it out soon.
• BTW, next episode to be released is with Bob Belderbos from PyBites. Should be later this week.

Michael:

• Facebook and Instagram start blocking news in Canada

Joke:

• day 1 and I hate it
