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

class foo:
    def __init__(self, **kwargs):
        for arg_name, arg_value in kwargs.items():
            setattr(self, arg_name, arg_value)

This requires arguments to be named:

obj = foo(arg1 = 1, arg2 = 2)
