Is it possible to create anonymous objects in Python?

Question

I\'m debugging some Python that takes, as input, a list of objects, each with some attributes.

I\'d like to hard-code some test values -- let\'s say, a list of four

Non classy:

def mock(**attrs):
    r = lambda:0
    r.__dict__ = attrs
    return r 

def test(a, b, c, d):
    print a.foo, b.foo, c.foo, d.foo

test(*[mock(foo=i) for i in xrange(1,5)])
# or
test(mock(foo=1), mock(foo=2), mock(foo=3), mock(foo=4))
