I got it. It makes sense now but my head was about to explode haha. the else inside the for loop is executing the first time the if is false. The else should be associated with the for instead of the if. Thanks a lot rgd1101

or is it just checking 9 % 2 and then moving on to the else statement when that evaluates to false?

and can I deselect that answer as the best one? He apparently missed the same thing I did originally.

it should run through and check: x = 9 9 % 2 9 % 3 and at that point it would be true so it wouldn't need to check 4 - 8 right?

I understand why the second section in the OP works now. x = 3 bypasses the for loop entirely the way it was written. That should check if 9 % 3 == 0 which would be true so it should return False. Am I missing something else?

Now I get another error when I get rid of the x-1. Oops, try again. Your function fails on is_prime(9). It returns True when it should return False. def is_prime(x): if x < 2: return False elif x == 2: return True else: for n in range(2, x): if...

Ah that's right. range() stop doesn't include the number it stops at so it wouldn't include 2. So when x = 3 it doesn't get checked. Nice

If I understand it correctly it would see if 3 / 2 has a remainder of 0 which of course would return False.

Thanks

How do I put it in code blocks? :p Thanks

So I'm going through the codecademy python course and one assignment is to create a function that can determine if a number is prime or not. I don't understand what the difference is between these two examples. The first one doesn't work but the second one does. I get this error message when...

Never mind I figured it out. I switched if ( x = 100) for if (x == 100). Thanks.

I wrote this program to practice the if statement. I can't get it to execute the else statement. Regardless of what the user enters it executes the if statement. //A program to let the user entera score and output if the score was perfect. #include <iostream> int main() { using namespace...
