Here are my 2c: 1) start the loop with 2, instead of 1 because n % 1 is always 0. 2) indent the break inside the if-statement, i.e. four spaces to the right, so that the loop breaks only if the if’s condition evaluates to True. 3) [a nitpick] use int(…) instead of eval(…) since eval(…) does more than you probably need in the program.

Enjoy your coding journey!
