Reposting from from my newest duplicate of this issue (Issue 24677), which is
now closed:
I think that a trailing comma in function definition should be allowed also
after *.
Current situation with definitions:
def f(*args, ): pass # SyntaxError
def f(*, ): pass # SyntaxError
def f(*, a, ): pass # SyntaxError
def f(*, a=2, ): pass # SyntaxError
def f(a, ): pass # Ok
def f(, ): pass # SyntaxError – this should probably stay error
Corresponding calls:
f(*args, ) # Ok
f(*args, a, ) # Ok
f(*args, a=2, ) # Ok
f(a, ) # Ok
f(, ) # SyntaxError – this is why the corresponding def behavior should stay
My use case:
def f(*,
long = 1,
list = 2,
of = 3,
kwonly = 4,
parameters = 5,
):
...
