Python: Iterating through constructor's arguments

Question

I often find myself writing class constructors like this:

class foo:
    def __init__(self, arg1, arg2, arg3):
        self.arg1 = arg1
        self.arg2 = arg2
         


        

Answer 1

The most Pythonic way is what you've already written. If you are happy to require named arguments, you could do this:

class foo:
    def __init__(self, **kwargs):
        vars(self).update(kwargs)
