如何找出两个多维数组之间的差异

def find_diff(arr1, arr2, diff):
    for i in range(len(arr1)):
        if isinstance(arr1[i], list) and isinstance(arr2[i], list):
            find_diff(arr1[i], arr2[i], diff)
        else:
            if arr1[i] != arr2[i]:
                diff.append((arr1[i], arr2[i]))

# 示例多维数组
array1 = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
array2 = [[1, 2, 3], [4, 5, 7], [7, 8, 9]]

# 存储差异的列表
differences = []

# 查找差异
find_diff(array1, array2, differences)

# 打印差异
if len(differences) > 0:
    print("两个多维数组存在差异：")
    for diff in differences:
        print(f"{diff[0]} -> {diff[1]}")
else:
    print("两个多维数组相同")
