...     def __init__(self, val, val2):

...             self.val = val

...             self.val2 = val2

... 

>>> x = fooboo(10)

>>> y = gooboo(10, 20)

>>> isinstance(x, fooboo)

True

>>> isinstance(x, object)

True

>>> isinstance(x, gooboo)

False

>>> isinstance(y, gooboo)

True

>>> isinstance(y, fooboo)
