But to use generator expressions, wouldn't you need an extra pair of round brackets? eg identity = ''.join( ( chr(i) for i in xrange(256) ) ) with the extra spaces added for clarity. That is, the brackets after join make the function call, and the nested brackets make the generator. That, at least, is my understanding. -- Steven who is still using Python 2.3, and probably will be for quite some time -- http://mail.python.org/mailman/listinfo/python-list
