I strongly suspect you could do more than that. Welcome to the Python discussion forum. > I tried to code a program in Perl, but found that another guy already > finished this job in Python.

Then he can hardly complain if someone else re-writes it in their language of choice, can he? :-) > C:\Documents and Settings\mhg\Desktop\palcalc>shapes.py > EE... This, and the rest of your output, is from the call to ‘unittest.main’, Python's standard-library module for unit testing. > File "C:\Documents and Settings\mhg\Desktop\palcalc\shapes.py", line > 90, in __init__ > super(Container, self).__init__(xsize, ysize) > TypeError: object.__init__() takes no parameters The ‘super(Container, self)’ call asks for a ‘super’ object representing the (next) superclass of the type of ‘self’. In this case, as the error message indicates, the next superclass type is ‘object’ – the base type of all objects. Also as the error message indicates, the initialiser for ‘object’ doesn't accept the parameters being passed. > class Container(object): > """Container to store a number of non-overlapping rectangles.""" > def __init__(self, xsize=1200, ysize=800): > super(Container, self).__init__(xsize, ysize) > self.rect = Rectangle(0, 0, xsize, ysize) > self.boxes = [] > self.last_placement_strategy = 0 So, there's no sense in calling the superclass's ‘__init__’ method with parameters which won't be accepted because of the function signature. The next thing to do is to ask about the design of these classes (what is the intention of this initialiser?). But you say you're entirely new to it, and that the designer has no interest in it. What are your options for getting their interest and participating in this thread? -- \ “I cannot conceive that anybody will require multiplications at | `\ the rate of 40,000 or even 4,000 per hour …” —F.
