Thank you for this Jean-Paul. I did know about the identity of objects, but my curiosity is based on the 256 number. Are the 2^8 integers cached due to the internal loops, or is there any other specific reason? Is this something that can be controlled? -- http://mail.python.org/mailman/listinfo/python-list
