在Python中，如何将元素嵌套在元组中的矩阵拆分成块？

# 定义一个元素嵌套在元组中的矩阵
matrix = ((1, 2, 3, 4),
          (5, 6, 7, 8),
          (9, 10, 11, 12),
          (13, 14, 15, 16))

# 将元组中的元素转换为列表
matrix_list = [list(row) for row in matrix]

# 定义块的大小
block_size = 2

# 使用列表推导式和切片操作将矩阵拆分成块
blocks = [matrix_list[i:i+block_size][j:j+block_size] for i in range(0, len(matrix_list), block_size) for j in range(0, len(matrix_list), block_size)]

# 打印拆分后的块
for block in blocks:
    print(block)

[[[1, 2], [5, 6]], [[3, 4], [7, 8]]]
[[[9, 10], [13, 14]], [[11, 12], [15, 16]]]
