I am currently stuck at the the is_prime exercise. Below you can read what I tried so far...
I get this error message:
"Oops, try again. Your function fails on is_prime(4). It returns None when it should return False."
I tried to debug it by printing the answer to me, but when I do this it returns the right answer.
I have no Idea how this is happening since it is working if I use print instead of return.
In my code below I commented out when it should return. Also for debug reasons you can choose the number.
x = int(raw_input("Choose a Number:")) testing = range(2,x-1) def is_prime(x): if x == 1 or x == 0: print "non Prime" #return False elif x <= 3: print "Prime" #return True for n in testing: if x%n != 0: print "Prime" #return True else: print "non Prime" #return False break
