Your function fails on is_prime(9). It returns True when it should return False.
My function is failing when I input Prime Numbers in it. I'm assuming that it keeps dividing by 0 in the last loop, however, even when I add "break," after the return statements, the function still spits out the error.
def is_prime(x): if x < 2: return False elif x == 2: return True else: for n in range(2, x): if x % n == 0: return False break else: return True break
