Well, "permanent temporary file" does sound odd. By the way, NamedTemporaryFile returns a proxy instead of the file itself. In some rare cases that could be a problem. Would mktemp() really be dangerous if you used it like this, def new_game(directory): for _retry in range(3): filename = mktemp("game_", ".json", dir=directory) try: return open(filename, "x") except FileExistsError: pass raise FileExistsError with the "x" mode? _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
