My 1st /prog/ram

So I took /prog/'s advice and started learning python:

Here is my first ever program that is not copypasted from the tutorial. (I went further by not ONLY having it say 'too high' or 'too low' or 'you guessed it')

Am I doing it right or is declaring 5 variables a waste of time?
Why cant I just say
if a < 5:
    print('way too low') #?
why does it have to be a variable?

I still wish python had a case statement ;_;
