did you read the string chapter in the tutorial ? http://docs.python.org/tut/node5.html#SECTION005120000000000000000 around the middle of that chapter, there's a section on slicing: "substrings can be specified with the slice notation: two indices separated by a colon" </F> -- http://mail.python.org/mailman/listinfo/python-list
