colpage.py

It's just weird, not wrong.

Honestly, I would say despite not being wrong, it is still quite wrong.

__init__ can only return None and by convention we never do this explicitly for __init__.
The function is "wrong" because just like this thread shows, it confuses people.

Just write this and avoid confusion:

class colpage:
    def __init__(self, gutter=None, width=None, height=None):
        self.geometry( gutter=gutter, width=width, height=height)

Though I think changes should still be made to make attributes clearer and there is no need to use that function to both set and get these attributes.  As a C programmer I would think you would hate a function with an unpredictable return type.
