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
