Hi guys! i've got a little problem with my code. I really can't understanding what's wrong.

Can you help me please ?

Thanks.

Oops, try again. Your function fails on is_prime(5). It returns False when it should return True.

```
def is_prime(x):
if x==0 or x==1:
return False
elif x==2:
return True
else:
for n in range(2,x-1):
if abs(x/n-round(x/n))==0:
return False
break
return True
```
