如何将“正方形”二维数组映射到切换坐标？(拼音)

def map_to_snake_coordinates(square_array):
    n = len(square_array)
    snake_coordinates = []
    for i in range(n):
        row = []
        for j in range(n):
            if i % 2 == 0:
                row.append((n-1-j, i))
            else:
                row.append((j, i))
        snake_coordinates.append(row)
    return snake_coordinates

# 示例用法
square_array = [[1, 2, 3],
                [4, 5, 6],
                [7, 8, 9]]
snake_coordinates = map_to_snake_coordinates(square_array)
print(snake_coordinates)

[[(2, 0), (1, 0), (0, 0)],
 [(0, 1), (1, 1), (2, 1)],
 [(2, 2), (1, 2), (0, 2)]]
