Kata

The task:

There are some pieces on the chessboard, but only two are used in this Kata: the chess knight (K) and any other piece (let's say k).

Your task is to implement a function that returns True if the conditional piece(k) is threatened by the knight(K), and return False if the conditional piece(k) is not threatened by the knight(K).

Some notes:

• ♘ Chess knight K
• � Conditional chess piece k

The function parameter is a chessboard with different arrangements of the above two pieces.

Chessboard example:

• 1 - black cell
• 0 - white cell

chess_board = [
    [0, 1, 0, 1, 0, 1, 0, 1], 
    [1, 0, 1, 0, 1, 0, 1, 0],
    [0, 1, 0, 1, 0, 1, 0, 1], 
    [1, 0, 1, 0, 1, 0, 1, 0], 
    [0, 1, 0, 1, 0, 1, 0, 1], 
    [1, 0, 1, 0, 1, 0, 1, 0], 
    [0, 1, 0, 1, 0, 1, 0, 1], 
    [1, 0, 1, 0, 1, 0, 1, 0]]

Chessboard example with different arrangements of two pieces:

chess_board = [
    [0, 1, 0, 'k', 0, 1, 0, 1], 
    [1, 0, 1, 0, 'K', 0, 1,0], 
    [0, 1, 0, 1, 0, 1, 0, 1], 
    [1, 0, 1, 0, 1, 0, 1, 0], 
    [0, 1, 0, 1, 0, 1, 0, 1], 
    [1, 0, 1, 0, 1, 0, 1, 0], 
    [0, 1, 0, 1, 0, 1, 0, 1], 
    [1, 0, 1, 0, 1, 0, 1, 0]]

If you suddenly forgot how a chess knight can walk, then here's a hint for you:
