It won't work with anything which isn't a number: py> min("hello", "goodbye") 'goodbye' But the max trick fails: py> -max(-"hello", -"goodbye") Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: bad operand type for unary -: 'str' If you want to write your own min without using the built-in, there is only one correct way to do it that works for all objects: def min(a, b): if a < b: return a return b Well, more than one way -- you can change the "a < b" to "a <= b" if you prefer. Or reverse the test and use >, or similar, but you know what I mean. -- Steve _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
