I am hoping to change the self.dict for each subclass. I realize that
I could save self.dict to file and then load in different dicts each
time I get a new instance of class. But I want to be able to make
subclasses of map that each have different self.dict. Then when I need
to use them, just import the module and use the specific dict, instead
of having to keep track of a separate dictionary file. I am new to
this, but I thought that this would be a regular thing to do in
python, because people must make classes in the interactive console
and then export them somehow for later use.
Thank you for your responses.
