A bare * indicates that the arguments that follow it are keyword-only:
>>> def f(a, b=2, *, c=3):
... print("a = {}, b = {}, c = {}".format(a, b, c))
...
>>> f(10)
a = 10, b = 2, c = 3
>>> f(10, 20)
a = 10, b = 20, c = 3
>>> f(10, 20, 30)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: f() takes from 1 to 2 positional arguments but 3 were given
>>> f(10, 20, c=30)
a = 10, b = 20, c = 30
