def is_even(num:int) -> bool:
    if x < 0:
        x = x * (-1)
    if x == 0:
        return True
    elif x == 1:
        return False
    elif x == 2:
        return True
    elif x == 3:
        return False
    elif x == 4:
        return True
    elif x == 5:
        return False
    elif x == 6:

    elif x == 7:

Here, I optimised it:

private function is_even(integer): 
    integer = 2;
    return True;

Yes, and it only returns, “I can’t even”
