I just try it and see what works ;).

The general idea is that if it is module-level it can be pickled and
if it is defined inside of something else it cannot. It depends
though.

"partial" takes a function and returns it with arguments "filled in":

    from functools import partial

    def add(a, b):
        return a + b

    add5 = partial(add, 5)

    print(add5(10)) # Returns 15 == 5 + 10

Never mind that, though, as Peter Otten's code (with my very minor
suggested modifications) if by far the cleanest method of the two and
is arguably more correct too.
