*Looks* better than the monkey business. Perhaps I should point out to those of the studio audience who are huddled in an ASCII bunker (if any) that string.letters provides the characters considered to be alphabetic in whatever the locale is currently set to. There is no guarantee that the operating system won't permit filenames containing other characters, ones that the file's creator would quite reasonably consider to be alphabetic. And of course there are languages that have characters that one would not want to strip but can scarcely be described as alphanumeric. >>> import os >>> os.listdir(u'.') [u'\xc9t\xe9_et_hiver.doc', u'\u041c\u043e\u0441\u043a\u0432\u0430.txt', u'\u5f20\u654f.txt'] >>> import string >>> string.letters 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ' Doing import locale; locale.setlocale(locale.LC_ALL, '') would make string.letters work (for me) with the first file above, but that's all. -- http://mail.python.org/mailman/listinfo/python-list
