Hello,

Can someone please look over my code. I get the correct responses but it tells me to switch to the opposite answer.

```
def is_prime(x):
for n in range(int(x-1)):
if x < 2:
return False # not prime
elif x % 2 == 0: # no remainders making it even
return False # not prime
else:
return True
print is_prime(0)
```

**Oops, try again. Your function fails on is_prime(0). It returns True when it should return False.**

Thank you very much.
