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

it is not working still

ERROR is:

Oops, try again. Your function fails on is_prime(-10). It returns True when it should return False.
