Because normcase() and friends never look at the filesystem. Of course, exists() and isdir() etc. do, and so does realpath(), but the pure parsing functions don't. They can be used without a working filesystem even. (E.g. you can import ntpath on a Unix box and happily parse Windows paths.) -- --Guido van Rossum (python.org/~guido) _______________________________________________ Python-Dev mailing list [email protected] http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
