It should be str_counts = dict((s, str_list.count(s)) for s in set(str_list)) or for Python < 2.4 str_counts = dict([(s, str_list.count(s)) for s in set(str_list)]) Note that this solution iterates str_list once for each element of str_list - the call to count traverses the entire list to create the count. I expect Paul Rubin's solution will be dramatically faster for large lists as it only iterates str_list once. Kent -- http://mail.python.org/mailman/listinfo/python-list
