C argument errors and Python arguments error are different.
For example:
all(4,4,4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: all() takes exactly one argument (3 given)
def func(a):pass
a(4,4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: func() takes exactly 1 positional argument (2 given)
I do not know which error message is better.
I think the second example's (func) error message is better.
Though feel free to vote by commenting on this bug.
Another example with not enough arguments given:
hasattr(4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: hasattr expected 2 arguments, got 1
func()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: func() takes exactly 1 argument (0 given)
I don't know which of this error messages are better.

This is won't fix at least for now. The way arguments to C functions are parsed prevents them from ever really being the same. Specific improvements can be considered.
