Its not another meaning, its the current meaning. Kent is just pointing out that while the default cmp currently returns -1,0,1 there is nothing to stop a user defined cmp fom returning any negative or positive number instead of -1,1. And cmp() calls any user defined cmp under the hood. In theory the standard cmp could be changed in future although its unlikely.. So while it is a nice trick it cannot be relied upon since it depends on a detail of implementation. In practice I suspect you are fairly safe :-) Alan G _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
