根据其他兄弟值更新多维数组的值

def update_array(arr):
    for i in range(len(arr)):
        if isinstance(arr[i], list):
            update_array(arr[i])  # 递归遍历子数组
        elif arr[i] == 0:
            siblings = [x for x in arr if isinstance(x, int) and x != 0]  # 获取兄弟元素列表
            if siblings:
                avg = sum(siblings) / len(siblings)  # 计算兄弟元素的平均值
                arr[i] = avg  # 更新目标元素的值

# 示例多维数组
array = [[1, 2, 0, 4], [0, 6, 7, 8], [9, 0, 11, 12]]
update_array(array)
print(array)

[[1, 2, 6.0, 4], [8.0, 6, 7, 8], [9, 6.0, 11, 12]]
