Variable arity minimum and maximum

In Python, the min and max functions are variable arity:

Define your own versions of these funtions—call them minimum and maximum. They should raise a TypeError if called with 0 or 1 arguments; if called with 2 or more arguments, they should calculate the minimum or maximum appropriately. Here’s an example interaction:

>>> maximum(1,2,3,4)
4
>>> minimum(1,2,3,4)
1
>>> maximum(*range(0,1000))
999
>>> maximum()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: maximum() missing 2 required positional arguments: '
first' and 'second'
>>> minimum(1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: minimum() missing 1 required positional argument: 's
econd'
>>> minimum(1,2)
1

(Look at help(min) for info on how the real, Python versions of these functions work—they’re a little more complicated than what we’re asking for.)
