This is the way to do it python, and it has its advantages: 1 docstring,
1 way do do it, 1 interface.

Yes, I see. Actually I do now realize that even in Java I use method
overloading mostly to implement optional arguments anyway, like:

void constructor(){this.foo='foo'; this.initotherstuff();}
void constructor(int x) {this.x=x; this.constructor();}

and so on.

So most of the time the idiom above is exactly what I need, as the
versions of the function share code anyway.

But there are also cases where they do something completely different -
in these cases I might use one of the other solutions provided here or
simply make two or three functions and name them appropiately.

I do now see that the pythonic approach is the "best" for most cases,
but I really loved to see that you *can* do overloading in a convenient
way if you really want to :D Those decorators just rock :D

You can do, see packages such as PEAK rules. They offer not only type-based overloading, but also value-based.
