Normally you don't need them. Write it this way: intX_asString = str(intX) The "dunder" methods ("d"ouble "under"score, leading and trailing), also called "magic methods", are the implementations of various special features. For instance, indexing foo[1] is implemented using the __getitem__ method. Here's a list: http://docs.python.org/3.3/reference/datamodel.html#special-method-names You'll seldom, if ever, call these methods directly. By the way, when you're asking a completely new question, it usually helps to do so as a brand new thread (not a reply) and with a new subject line. Otherwise, you risk people losing the new question among the discussion of the old. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
