Python Help me please

2. Implement function q2(num, string1, string2) so that it returns True if the input strings are the same length and differ at exactly num character positions, and returns False otherwise. NOTE: Use a simple loop comparing corresponding characters directly. You may not use any string methods. For example >>> q2 (1, "bat", "bet") True >>> q2 (1, "art", "rat") False >>> q2 (1, "art", "ran") False >>> q2 (2, "art", "rat") True >>> q2 (3, "art", "ran") True >>> q2 (2, "abcde", "abada") True >>> q2 (99, "abcde", "abada") False >>> q2 (-1, "abcde", "abada") False
