Reports discrepancies between declared parameters and actual arguments, as well as incorrect arguments, for example, duplicate named arguments, and incorrect argument order.

Example:

class Foo:
    def __call__ (self, p1: int, *, p2: str = "%"):
        return p2 * p1

bar = Foo()
bar. __call__ () # unfilled parameter
bar(5, "#") # unexpected argument

The correct code fragment looks at follows:

class Foo:
    def __call__ (self, p1: int, *, p2: str = "%"):
        return p2 * p1

bar = Foo()
bar. __call__ (5)
bar(5, p2="#")
