iterate over class properties?

[Gribouillis]

You could add this to my code

def property_summary(self):
    return {k: getattr(self, k) for k in self.property_names()}

def add_property_summary(cls):
    add_property_names(cls)
    cls.property_summary = property_summary
    return cls

Then instead of decorating videofile with add_property_names, decorate it with add_property_summary

if __name__ == '__main__':
    
    @add_property_summary
    class videofile:
        ...

you can then get a dict with

movieitem.property_summary()
