Thanks for helping me clarify on how to use super() in Py2+. That really
worked!
>>> class B(A):
... def __init__(self, module):
... self.module = A.log(self, module)
... print self.module # printing here is completely unnecessary
in a good OOP language
...
>>> c = B('system')
logged
>>> class B(A):
... def __init__(self, module):
... print super(B, self).log('system') # printing here is
completely unnecessary in a good OOP language
...
>>> c = B('system')
logged
>>>
When an instance of a class is created, all codes within that instance block
should be executed. That's my understanding of OOP.
Thanks everyone!
