If i assign a valid value to a variable the variable is also valid...thats...thats...

If you still cannot grasp this simple concept then i fear i may not be able to help you understand Steven.

A "for x in range(N)" is just so you can loop N times. And since changing the values in a list whilst looping over it is the sport of fools then what usefulness would a variable be for such a construct? You have failed to prove the usefulness of this syntax Steven. I suggest you go back and read over my posts again and then marinate on the contents for a while. THEN come back with an argument based in reality and we will try again...You know at one time i actually considered you a formidable foe, well these times they are a chang'in right Dylan? -- http://mail.python.org/mailman/listinfo/python-list
