I have some trouble with this "prime" problem. Can you please explain why the is_prime(2) shows None with the code i wrote.Also can you tell me if there is a better way to write the code. I don't want to see other examples because I want to improve mine. Thank you and have a nice day.

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