Oops, try again. Your function fails on is_prime(2). It returns False when it should return True.

it blows my mind as at the hint it even says "all numbers less than 2 are not prime numbers!"

```
def is_prime(x):
if x > 2:
for n in range(2, x -1):
if x % n == 0:
return False
else:
return True
elif x <= 2:
return False
```
