bug: target-version not respected when formatting with statement

[ziadkh0]

Formatting the following code with target-version set to "py39" and line-length set to 10 (just for the example):

with A() as a, B() as b:
    pass

Expected output similar to:

with \
    A() as a, \
    B() as b \
:
    pass

Actual output:

with (
    A() as a,
    B() as b,
):
    pass

Playground

Support for using grouping parentheses to break the with statement in multiple lines was added in version 3.10, see: https://docs.python.org/3/reference/compound_stmts.html#the-with-statement

Thanks for opening the issue!

It was only formally added to the language spec in Python 3.10. However, it was (initially only accidentally) made valid syntax in Python 3.9. This definitely isn't going to be reverted in CPython, so it's entirely safe to assume that with items can be parenthesized on Python 3.9. Black also uses parenthesized with items on Python 3.9, and I think it's good for us to be consistent with Black here. (Actually this was recently discussed again at psf/black#4488, but they decided to keep their current behaviour.)

Is this behaviour causing an issue for you somewhere? :-)

Thank you for the quick reply!
I didn't that 😮
I just check it, and I can confirm that it's not causing an issues 😄
I guess this issue can be closed
