confusing-with-statement / W0124ΒΆ

Message emitted:

Following "as" with another context manager looks like a tuple.


Emitted when a `with` statement component returns multiple values and uses name binding with `as` only for a part of those values, as in with ctx() as a, b. This can be misleading, since it's not clear if the context manager returns a tuple or if the node without a name binding is another context manager.

Problematic code:

with open("file.txt", "w") as fh1, fh2:  # [confusing-with-statement]

Correct code:

with open("file.txt", "w", encoding="utf8") as fh1:
    with open("file.txt", "w", encoding="utf8") as fh2:
