Oops, try again. Your function fails on is_prime(9). It returns True when it should return False.

my code looks fine, i don't understand what's wrong, kindly help me out

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