Ok, I prefer to think that I could be more specific.
So, let's try again.
Supose that I want to create two methos (inside a
class) with exactly same name, but number of
parameters different:

class myClass:
     myAttribute = 0
     def myMethod(self):
          self.myAttribute += 1
     def myMethod(self, myValue):
          self.myAttribute += myValue

Both method hold same identifier, the only difference
in them signture are parameters.
How could I simulate the situation above, using the
language dynamic link (or polymorphism, as you
prefer)?

Look, I don't want to use things like:

....
      def myMethod(self, myValue=None):
           if(not myValue):
                self.myAttribute += 1
           else:
                self.myAttribute += myValue
....

I want to use the power of polymorphism to modelate
the problem.

           Thanks and best regards
