Just do: a() or b() or c() The "or" operation has what's known as "short-circuit" semantics. That means, if the first operand is true, it doesn't evaluate the second operand. Just make sure that a(), b(), and c() all return something which is true if they succeed and false otherwise. -- https://mail.python.org/mailman/listinfo/python-list
