others already gave good responses, so mine are short. > 1)where do `is` and `==` yield the same results?
"is" is object identity comparison while "==" is object value comparison > 2)where do they not yield the same results? they give different results when you have two different objects regardless of the equality of their values. > 3)is there a special method for `is'. no, not really. you can use id() and '==' to proxy for is: a is b <==> id(a) == id(b) > 4)Pointers to docs are welcome. http://docs.python.org/lib/comparisons.html http://docs.python.org/ref/comparisons.html hope this helps! -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall, (c)2007,2001 http://corepython.com wesley.j.chun :: wescpy-at-gmail.com python training and technical consulting cyberweb.consulting : silicon valley, ca http://cyberwebconsulting.com _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
