On: Show HN: Python micro event loop library (~250 LOC)

[svilen_dobrev]

thanks for pointing that out. Seems a thorough scan as features of whatsnew is due - since maybe 3.7?

For the record, ~language~ additions i found interesting (excluding type-hints):

  3.11:
   (Base)ExceptionGroups ; (Base)Exception.add_note() + __notes__
   modules: tomllib
  3.10:
   Parenthesized context managers 
   Structural Pattern Matching - match..:case.. 
   builtins: aiter(), anext() 
  3.9:
   dict | dict ; dict |= dict
   for a in *x,*y: ...    #no need of (*x,*y)
   str.removeprefix , str.removesuffix
   Any valid expression can now be used as a decorator
   modules: zoneinfo , graphlib
  3.8:
   Assignment expressions
   Positional-only parameters
   f'{expr=}'
   Dict comprehensions and literals compute First the key and Second value
  3.7:
   builtins: breakpoint()
   __getattr__ and __dir__ of modules
   modules: contextvars , dataclasses

Misc:

3.10 zip(strict=True) 3.11 asyncio.TaskGroup (structured concurrency) enabled by ExceptionGroup

3.12 itertools.batched(L, n) — it replaces zip([iter(L)]n)

There was also the walrus operator

[svilen_dobrev → hyperbrainer]

that's the Assignment expressions, i.e. :=

True, I did not see that. My bad, sorry!
