It is unusual to assemble these tasks but not await them. Are we certain that they will be run at some point?

Well, so this code was working fine but ruff complained that the tasks were dangling: https://docs.astral.sh/ruff/rules/asyncio-dangling-task/.

So, the advice was to create a strong reference to the tasks. However, now ruff complains that tasks are assigned but never used. It feels like you can't win.

@cclauss ?

@cclauss you need to actually do a read&write conversation, not just write only please.

I was wrong... This usage is correct.

>>> import asyncio
>>> async def print_char(char: str) -> None:
...     print(char)
...
>>> async def run(chars: str) -> None:
...     _tasks = [asyncio.create_task(print_char(char)) for char in chars]
...
>>> asyncio.run(run("abcdefg"))
a
b
c
d
e
f
g

This changes things. Normally, ASYNC and RUF are off by default, so this change removes those rules and adds the default rules. https://docs.astral.sh/ruff/rules Let's run both just to be safe.

Oh, I see. Thanks.

This syntax would delete tasks as they are completed, as discussed in ruff rule RUF006.
