请解释<代码>[[0]*64, 范围(7)],范围(2)][部分,以及如何写上等值。
pieceHashes = [[[0]*64 for i in range(7)] for j in range(2)]
for color in WHITE, BLACK:
for piece in PAWN, KNIGHT, BISHOP, ROOK, QUEEN, KING:
for cord in range(64):
pieceHashes[color][piece][cord] = randint(0, maxint)
(let ((piece-array (make-array (2 7 64) :initial-element 0)))
(dolist (color `(,white ,black))
(dolist (piece `(,pawn ,knight ,bishop ,rook ,queen ,king))
(loop for cord below 64
do (setf (aref piece-array color piece cord)
(random maxint))))))
It generates a three-dimensional array that has 64 x 7 x 2 elements. The array is then filled on the final line.
