It either succeeds or fails for the entire class. If it fails, you get an exception at class definition time: class A: pass class B: pass class C(A, B): pass class D(B, A): pass class E(C, D): pass Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: Cannot create a consistent method resolution order (MRO) for bases A, B ChrisA -- https://mail.python.org/mailman/listinfo/python-list
