Python: currying

Suppose we have an implementation of Python in which functions support currying. We write:


def f(x, y, z):
    print(x, y, z)

f(y=2)(1)(3)

What output will be generated?

It can be rather useful. If a language lets you implement currying yourself(preferably, within a couple of lines of code), it means it's worth using.
