Python class instance __dict__ doesn't contain all instance variables. Why?

Question

Here\'s a bit of a newbie Python question about instance variables.

Consider the following Python 2.7 class definition:

class Foo(object):
    a = 1
         


        

Answer 1

May this help you further?

>>> class X(object):

    def __getattribute__(self, name):
        print name
        return object.__getattribute__(self, name)


>>> l = dir(X())
__dict__
__members__
__methods__
__class__
>>> l
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__']
