Of course not. py> "2 #".islower(), "2 #".isupper() (False, False) py> not "2 #".islower(), "2 #".isupper() (True, False) "Is Lower" versus "Is Upper" is not a dichotomy. There are: - lowercase characters, like "abc" - uppercase characters, like "ABC" - characters which are neither lowercase nor uppercase, like "2 #" In unicode, there are also: - titlecase characters, like "DžLjῼ" If those characters don't show up for you, they are: U+01C5 LATIN CAPITAL LETTER D WITH SMALL LETTER Z WITH CARON U+01C8 LATIN CAPITAL LETTER L WITH SMALL LETTER J U+1FFC GREEK CAPITAL LETTER OMEGA WITH PROSGEGRAMMENI So not islower() is very different from isupper. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
