Is this a test? Do you want to see how smart we are? Or are you really
trying to find and correct the problems? If the latter please OH please
do as we have requested MANY TIMES - post the traceback.
I'm also concerned, considering the progress you've made in
understanding Python, that this program should stump you. To my eye
there are several syntax errors that stand out like a sore thumb.
Please look at the traceback, notice which line it complains about, then
look at each piece of that line to see whether is is a valid Python element.
Aside from all of that I think this is a pretty poor example of
programming. The use if bitwise operators instead of boolean is not
wrong, but could be misleading or give incorrect results in other
situations. There are no user input checks to reject nicely non-integer
input. There are statements that can be factored out of the loop.
