使用python遍历嵌套列表以获取特定值

def find_value(nested_list, target):
    for item in nested_list:
        if isinstance(item, list):
            result = find_value(item, target)
            if result is not None:
                return result
        elif item == target:
            return item
    return None

nested_list = [1, 2, [3, 4, [5, 6]], 7, [8, [9, 10]]]
target = 6

result = find_value(nested_list, target)
if result is not None:
    print("找到了目标值:", result)
else:
    print("未找到目标值")

找到了目标值: 6
