intercepting method call

[Tripp Scott]

class A:

    def __validate__(self, methodName, args):
        # do some checking

    def x(self, foo, bar):
        # do something

what i would like is to have some validating routine
(either the said object's __validate__() or some
method from another object) be automatically invoked
whenever the target method x is called. can i do that
in Python?
