First of all, you haven't given us your whole program. I know this because
while you've defined the NOS function, it isn't actually called anywhere.
You must have left that part out.
Anyway, I think you're doing two things wrong:
1. You aren't capturing the user's input. The input() function returns
the user's input, but you aren't assigning this to a variable; it's just
being thrown away. You should call input() like this:
user_input = input(I)
(Also, it would probably be clearer to use a name like "prompt" instead
of "I".)
2. You aren't using the compound "if" statement correctly. You can't
do this (well, you CAN, but it won't do what you want):
if a == 1 or 2 or 3:
You should fully spell out each condition, like this:
if a == 1 or a == 2 or a == 3:
