After 5 years of Python, I don't even see self anymore (how zen).

Author could have written

    class Window(object):
        def __init__(self, min, max):
            if min > max:
                min, max = max, min
            self.min = min
            self.max = max

to avoid repetition. If many args are needed,

    def __init__(self, a,b,c,d,e,f,...):
        for k, v in locals().items():
            setattr(self, k, v)

Etc etc there are endless idiomatic ways to avoid boilerplate in Python
