I've submitted the following code:

I have tested this code in visual studio to verify it works when called. Genepy says "I tried is_prime(1) and it returned None." It's expecting a boolean True or False. When I call is_prime(1) with the same code in visual studio it says False, not None.

@BusterOfTheBeans Your function prints some result, but does not return anything (well, technically, it returns None). Update your function to return the result.

@mdk That may be a new case for the checker to generate a proper help message? "Maybe you forgot to return a value from your function?"
