# Is_prime

**stetim94**#3

a function ends the moment a return keyword is reached (even when return keyword is reached in loop)

so, for `x=9`

the first case tested by the loop is `n=2`

:

```
if 9 % 2 == 0
```

which evaluate to false. so else runs, True is returned, the function ends

What is the condition for a number to be a prime number? `x`

shouldnâ€™t be divislbe by any number in range, this is clearly not happening at the moment
