__getattr__ equivalent for methods

When an attribute is not found object.__getattr__ is called. Is there an eq开发者_开发百科uivalent way to intercept undefined methods?

There is no difference. A method is also an attribute. (If you want the method to have an implicit "self" argument, though, you'll have to do some more work to "bind" the method).

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
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'NoneType' object is not callable

you didn't return anything.

class A(object):

  def __getattr__(self, attr):
    return attr

should work
