should actually copy the traceback and place it in your message so that we
can see what is going wrong.

But you have some other problems.  You keep getting a new random number in
your while loop.  You should just get the random number at the beginning,
and after each incorrect guess ask for your input again.  So, fix that, then
run the program and send us back your traceback with the code
