1st, I presume you mean that you want back ['foo', 'bar', 'blah', 'hm', 'lala'] instead of [foo, bar, blah, hm, lala] (which would presume you have variables named as such, which is kinda funky) That said... Well, I'm sure there are scads of ways to do this. I know regexps can do it fairly cleanly: >>> import re >>> r = re.compile(r'\w+') >>> s = 'foo bar- blah/hm.lala' >>> s2 = 'foo////bbbar.. xyz' >>> r.findall(s) ['foo', 'bar', 'blah', 'hm', 'lala'] >>> r.findall(s2) ['foo', 'bbbar', 'xyz'] The regexp in question (r'\w+') translates to "one or more 'word' character". The definition of a 'word' character depends on your locale/encoding, but would at a minimum include your standard alphabet, and digits. If you're not interested in digits, and only want 26*2 letters, you can use >>> r = re.compile(r'[a-zA-Z]+') instead (which would be "one or more letters in the set [a-zA-Z]"). -tkc -- http://mail.python.org/mailman/listinfo/python-list
