Ahh, thank you. That explains why Fredrick's and Jean-Paul's example did not work, but mine did (I was using *small* integers). Ok, well I definitely get the picture. Use the "is" operator for what it was intended for, or deal with broken code ;-) Thanks a lot guys. -- http://mail.python.org/mailman/listinfo/python-list
