Wouldn't this be a lot simpler if you just used straight inheritance?

class A(object):
    _header = "A's header"
    def render(self):
        return self._header + 'Foo Bar Baz'

class B(A):
    _header = "B's header"

I know this is probably just a "stripped to the minimum example", so
using inheritance may not work in your real problem. But it ought to
be worth a look.
