Your syntax is correct...the error you get back is the clue: either "s" or "e" fails to meet the criteria of being "integers or None". Check your values/types of those two variables before this call and you'll likely find that one or both is some other data-type. >>> text="hello world" >>> s = 4 >>> e = 5 >>> text[s:e] 'o' Darn those error messages that give away the answer... ;) -tkc -- http://mail.python.org/mailman/listinfo/python-list
