如何迭代嵌套数组/散列并从中检索数据

def search_nested_array(arr, target):
    for item in arr:
        if isinstance(item, list):  # 判断当前元素是否为数组
            result = search_nested_array(item, target)  # 递归调用自身进行遍历
            if result is not None:
                return result
        elif item == target:  # 找到目标数据
            return item
    return None  # 遍历完整个数组，未找到目标数据

# 示例数据
nested_array = [1, 2, [3, 4, [5, 6]], 7, [8, [9, 10]]]
target_data = 6

# 调用函数进行检索
result = search_nested_array(nested_array, target_data)

if result is not None:
    print("找到目标数据:", result)
else:
    print("未找到目标数据")

def search_nested_dict(dictionary, target):
    for key, value in dictionary.items():
        if isinstance(value, dict):  # 判断当前值是否为字典
            result = search_nested_dict(value, target)  # 递归调用自身进行遍历
            if result is not None:
                return result
        elif value == target:  # 找到目标数据
            return value
    return None  # 遍历完整个散列，未找到目标数据

# 示例数据
nested_dict = {
    'a': 1,
    'b': 2,
    'c': {
        'd': 3,
        'e': {
            'f': 4,
            'g': 5
        }
    },
    'h': {
        'i': 6,
        'j': {
            'k': 7,
            'l': 8
        }
    }
}
target_data = 5

# 调用函数进行检索
result = search_nested_dict(nested_dict, target_data)

if result is not None:
    print("找到目标数据:", result)
else:
    print("未找到目标数据")
