How do I copy **kwargs to self?

Question

Is there a way that I can define __init__ so keywords defined in **kwargs are assigned to the class?

For example, if I were to initialize a ValidationRule class with ValidationRule(other='email'), the value for self.other should be added to the class without having to explicitly name every possible kwarg.

class ValidationRule:
    def __init__(self, **kwargs):
        # code to assign **kwargs to .self

Answer 1

This may not be the cleanest way, but it works:

class ValidationRule: 
    def __init__(self, **kwargs): 
        self.__dict__.update(kwargs)

I think I prefer ony's solution because it restricts available properties to keep you out of trouble when your input comes from external sources.
