execute a function before and after any method of a parent class

[TP]

Hi everybody,

I would like to be able to specialize an existing class A, so as to obtain a
class B(A), with all methods of B being the methods of A preceded by a
special method of B called _before_any_method_of_A( self ), and followed by
a special method of B called _after_any_method_of_A( self ).

The goal is to avoid to redefine explicitly in B all methods of A.

Is this possible in Python?

Thanks a lot

Julien
