How can I denote unused function arguments?

Question

When \"deconstructing\" a tuple, I can use _ to denote tuple elements I\'m not interested in, e.g.

>>> a,_,_ = (1,2,3)
>>> a
1         


        

Answer 1

In order to avoid "unused variable" inspection messages for unused *args and/or **kwargs, I replace args and kwargs by _ and __ :

def f(a, b, *_, **__):
    ...

In addition to remove messages, it clearly shows that you don't care about these arguments.

I can't say if it is a really universal solution, but it worked everywhere I've used it until now.
