No, that's not it. There is an asymmetry between the way a method is declared and the way it is 
invoked. In the declaration, you list 'self' as an explicit parameter, e.g.
   def CreateGrid(self, *_args, **_kwargs)
but at the point of call the 'self' argument is implicit, it is the object on which the method is 
invoked. So the call
   self.grid1.CreateGrid(100, 6)
will call CreateGrid with the three arguments (self.grid1, 100, 6)

I don't know what the actual problem is but I'm pretty sure this isn't the solution.

jrlen, the error trace you sent looks incomplete, it doesn't show any of your code. Is there more of it?
