函数定义中的星号（*）替代

Question

Pylint complains when I am using an asterisk in a function call

def f(*args):
    # Some code

f(1, 2, 3,)

The output given by pylint:

pylint failed:
Used * or ** magic (star-args)

Is there an alternative to using * in function definitions, that renders the same result?

I need the code to validate through pylint because it is a school assignment. I don't think it is a legit warning but I have to do as pylint says.

Answer 1

Pylint is highly configurable and can be rather a nuisance when it comes to certain things. Even the star-args (W0142) rule description shows it is merely a warning:

Used * or ** magic . Used when a function or method is called using *args or **kwargs to dispatch arguments. This doesn't improve readability and should be used with care.

Just disable the warning for functions where you are certain using *args is the correct thing to do, rather than try and work around PyLint:

def f(*args):  # pylint: disable=star-args
    # Some code

Your only alternative is to accept one argument that you treat as a sequence, then pass in a tuple or list instead:

def f(arg):
    # Some code

f((1, 2, 3))

but I seriously doubt you'll be failed for using a # pylint disable=... comment.
