This has one potential problem:  If your function has a data attribute,
it will try to run it.  By this I mean:

self.number=42 

hasattr(self, 'number') is true.

You may want to check:

method = getattr(self, method_name, None) # return None if doesn't exit
if callable(method):
   method(*args, **kwargs)
