I'd guessed the OP was in Israel from his e-mail address. If that's what Outlook Express is doing, then that's conclusive proof :-) An aside to the OP: Pardon my ignorance, but does Hebrew have upper and lower case? > You may have to do some setup > of your locale for proper handling of unicode.isupper, etc., Whatever gave you that impression? > but I hope this > gives you a jump start on your problem. > > -- Paul > > > import sys > import re > > uppers = u"".join( unichr(i) for i in range(sys.maxunicode) > if unichr(i).isupper() ) > lowers = u"".join( unichr(i) for i in range(sys.maxunicode) > if unichr(i).islower() ) Just in case the OP is running a 32-bit unicode implementation, you might want to make that xrange, not range :-) > > allUpperRe = ur"\b[%s]+\b" % uppers > allLowerRe = ur"\b[%s]+\b" % lowers > capWordRe = ur"\b[%s][%s]+\b" % (uppers,lowers) > > regexes = [ > (allUpperRe, "all upper"), > (allLowerRe, "all lower"), > (capWordRe, "title case"), > ] > for reString,label in regexes: > reg = re.compile(reString) > result = reg.findall(u" YES yes Yes ") > print label,":",result > > Prints: > all upper : [u'YES'] > all lower : [u'yes'] > title case : [u'Yes'] Cheers, John -- http://mail.python.org/mailman/listinfo/python-list
