Different methods with same name but different signature?

Since you don't need to specify argument types in Python function
definitions, what you describe is not reasonably possible.  Python
functions do not have signatures in the way that a C++ programmer
means that term.  In any case, I'd be willing to bet that you don't
really need to have multiple functions with one name.

You can simply make one function of that name, and have it branch or
otherwise act appropriately based on the argument types.  Not only is
this nicer than the C++ way, it will probably be easier for someone
else to understand when they read your code.

I'll take Python's flavor of polymorphism over C++'s any day.  No contest.
