That was mentioned explicitly under "Incompatibilities" (last sentence): - Currently, the '%u', '%x', '%X' and '%o' string formatting operators and the hex() and oct() built-in functions behave differently for negative numbers: negative short ints are formatted as unsigned C long, while negative long ints are formatted with a minus sign. This will be changed to use the long int semantics in all cases (but without the trailing 'L' that currently distinguishes the output of hex() and oct() for long ints). ... Since it wasn't mentioned explicitly again under "Transition", but the trailing 'L' on repr() was explicitly mentioned twice under "Transition", the least strained logic-chopping reading is that losing the 'L' for hex() and oct() was intended to be done along with the other changes in the paragraph quoted above. > I think they should be considered just as sticky as the trailing 'L' for > repr(). Given that the "least strained" reading above missed its target release, and the purpose of target releases was to minimize annoying changes, I agree it should be left for P3K now regardless. I'll change the PEP accordingly to make this explicit. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
