Python expects it all right, but it intentionally converts the value to a boolean. The 'in' operator calls PySequence_Contains, which returns a boolean value at the C level. User-supplied __contains__ is implemented as an adaptor in typeobject.c (slot_sq_contains). It takes the value returned by your __contains__ implementation and converts it to 0 or 1. I don't think you can overload 'in' as you want without pervasive changes to CPython source code. -- http://mail.python.org/mailman/listinfo/python-list
