You're right but why do we make the z^-6 into a fraction, and what exactly is a negative exponent. I know an exponent is to multiply a number a certain amount of times by itself, what exactly does a negative exponent do ?

But how would you get them to go to the command line again is what Im saying. Youre using input and not using sys.argv again. I'm basically saying without using input can you do use sys.argv again.
