I'm wondering how I could make my is_prime function recursive. So far I'm kind of stuck on how to turn this for loop into a more recursive function. So far I'm coming up empty.

I suspect that I may have to have two functions that call upon eachother somehow, but I'm having a hard time coming up with a possibility. Any thoughts?

```
def is_prime(x):
if x < 2:
return False
for i in range(2,x):
if x%i==0:
return False
return True
print is_prime(11)
```
