Need help ASAP!! Please help (Programming Language PYTHON)

Thank You!

-- The following is the combination of the affine cipher and the Hill cipher. The key for the cipher is a 2-by-2 matrix A and a 2-dimensional vector (b 1 ,b 2 ). Just like in the Hill cipher, the numerical plaintext is split into blocks of length 2; and each block (x 1 ,x 2 ) is encrypted using the function

(x 1 ,x 2 ) 7 [(x 1 ,x 2 )A + (b 1 ,b 2 )] (mod 26).

An agent was able to intercept a snippet of plaintext and the corresponding ciphertext is RFKNMC . Please design a known plaintext attack on this cipher and recover the encryption key. Answer should include the following :-

1) The computer code that is used to produce the answer

2) The Matrix A and the vector (b1, b2)

3) Description of method that is used to find the 2 by 2 Matrix A and the vector (b1, b2)
