AttributeError when trying to use tkFont
If you look at the docs for tkFont, you'll see that the problem is that tkFont.Font requires a root argument - i.e. a parent widget. Fix this by moving the call to tkFont.Font below where you create the root window, then add self.root as a keyword argument, like so:
self.root = Tk()self.titleFont = tkFont.Font(root=self.root, family='Helvetica', size=24, weight='bold') ^^^^^^^^^^^^^^You haven't gotten to this bug yet, but there are problems with the next line - I think you meant to write self.root.option_add rather than self.option_add, and I don't know what you're trying to do with the *Label*font business.
