[Tutor] what's your name? (to a class)

The class has it, the instance doesn't. That said, you are looking for self.__class__.__name__ ...

... which you do use here.

I do not get it. The __class__.__name__ thing works great for me:

  >>> class Foo():
  ...     def whoami(self):
  ...         return self.__class__.__name__
  ...
  >>> f = Foo()
  >>> f.whoami()
  'Foo'
  >>> class Bar(Foo):
  ...     pass
  ... 
  >>> b = Bar()
  >>> b.whoami()
  'Bar'

Please be a bit more specific about your problem, because the problem
you described obviously does not exist ;).
