Question

When an attribute is not found object.__getattr__ is called. Is there an equivalent way to intercept undefined methods?

Answer 1

Methods are attributes too. __getattr__ works the same for them:

class A(object):

  def __getattr__(self, attr):
    print attr

Then try:

>>> a = A()
>>> a.thing
thing
>>> a.thing()
thing

  File "<stdin>", line 1, in <module>
