The error message is :

Oops, try again. Your function fails on is_prime(3). It returns False when it should return True.

I have this error with all numbers, divisible by 3.

```
def is_prime(x):
if x > 2:
for n in range(2,(x-1)):
if x % n != 0:
return True
else:
return False
if x == 2:
return True
else:
return False
print is_prime(9)
```
