Why not?

>>> def f(a, b, c=3): pass
...
>>> f()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: f() missing 2 required positional arguments: 'a' and 'b'
>>> f(1, 2, 3, 4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: f() takes from 2 to 3 positional arguments but 4 were given
