8개씩 잘라서 아스키로 변환해보면 다음과 같습니다.

 

bi = '010011100101011001000011010101000100011001000100010101100010000001001011010001100010000001001010010011000100010101011010010001010101001001001011010100100100101000100000010100100100010101010101001000000100101101000110010101010101001001010000001000000101101001001010001000000101001000100000010110000100011001000110010101010010000001010101010100100101000000100000010100100100010101010101001000000101001001001100010010110101100101000010010101100101000000100000010110100100101000100000010001110100001101010010010110100101010101010100010010110101011101011010010010100100110101010110010010010101000001011001010100100100100101010101'
