So my error message said "Oops, try again. Your function fails on is_prime(9). It returns True when it should return False." but I don't see why it returned True when x is 9. Can someone help me?

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