OK, bad example. But assume I have the same method in both classes and
want to call the method in the parent.

I just want to know what is the best way to do this.
As for an example, I would say the __init__ method where the parent
class do some initialization, to be sure that everything is set up
correctly I would call the parents class __init__ method before doing
something else.

Slashes in linux indicate a directory path. You use them when trying to specify
