I don't see much value autoassignining args. I do see being useful at times to auto-assign kwargs.

  class Base(object):
      def __init__(self, *args, **kws):
          self.__dict__.update(kws)

  class Foo(Base):
      def__init__("foo", age=30):
          self.name = "foo"
          super(Foo, self).__init__("foo", age=30)

or you can do the same using a decorator for the init.

  def update(init_meth):
      def wrapped(self, *args, **kws):
          init_meth(self, *args, **kws)
          self.__dict__.update(kws)
      return wrapped

  class Foo(object):
      @update
      def__init__("foo", age=30):
          self.name = "foo"
