If you type 0xC, you get a number. Try it: >>> 0xC 12 '12' is the default python representation of the integer 0xC. Internally, it is (I guess) stored as a 4 byte chunk of memory; that is, a 32-bit long binary. There is _no difference_ between 0xC and 12: >>> 0xC is 12 True The hex() function (and oct() too) provides you with a different string representation from the default. If you want to change python to display integers in hex instead of decimal by default, I can't help you.. (well, maybe you could subclass int, and change __repr__ and __str__ to return hex strings) -- John. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
