Black: Trailing comma for function with one arg

Created on 2 Jun 2019  路  4Comments  路  Source: psf/black

A function with one argument keeps the trailing comma but if there are two it is stripped.

In:

def one(
    a,
):
    pass

def two(
    a,
    b,
):
    pass

Out

def one(a,):
    pass


def two(a, b):
    pass

That's a bug, one should be formatted like so:

def one(a):
    pass

I made pull request #891 with a potential fix. Please let me know if the approach makes sense and if you have any suggestions for improvement.

Looks like this was fixed in 9394de150ebf0adc426523f46dc08e8b2b2b0b63. Can this be closed?
