Sorry still doesn't make sense, I'll give it a try though:

class Demo(object):
     """Apparently a 'real-life coding situation'"""
     def __init__(self):
         # Look at http://docs.python.org/tutorial/classes.html
         # for init explanation.
         self.__class_var = self.fact(5)

     def fact(self, number):
         """Look at http://docs.python.org/tutorial/classes.html why you 
need
         self."""
         if number < 2:
             return(1)
         else:
             return_value = number * self.fact(number -1)
             return(return_value)


TEST = Demo()
# Print the 'private' class variable
print(TEST._Demo__class_var)
