Hi guys,

I am trying to solve this problem. But it says that the code fails on 3 as it return "false" here is my code ... any suggestions?

```
def is_prime (x):
if x ==0:
return False
if x<2:
return False
elif x == 2:
return True
else:
for n in range (2,x):
division = float (x/n)
if round(division,0)-division>0:
return True
else:
return False
```
