__getattr__ equivalent for methods

Question

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

Answer 1

Ways are also attributes. __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 

Answer 2

There is no difference. The method is also an attribute. (If you want the method to have an implicit “i” argument, you will have to do one more job to bind the method).

Answer 3

you have not returned anything.

 class A(object): def __getattr__(self, attr): return attr 

must work
