Because that's how private members work.  See "5.2.1 Identifiers (Names)" in
the Python Language Reference.

>>> class PropTest:
...     def __init__(self):
...         self.__prop3 = 3
...     def testprops(self):
...         print hasattr(self, '__prop3')
...         print hasattr(self, '_PropTest__prop3')
...
>>> dir(PropTest())
['_PropTest__prop3', '__doc__', '__init__', '__module__', 'testprops']
>>> PropTest().testprops()
False
True
>>>

You're probably better off not using private members anyway.
