如何改进清理嵌套对象方法以同时删除空对象

def clean_nested_objects(obj):
    if isinstance(obj, dict):
        # 遍历字典的键值对
        for key, value in list(obj.items()):
            if value is None:
                # 删除空值
                del obj[key]
            elif isinstance(value, (dict, list)):
                # 递归处理嵌套对象
                clean_nested_objects(value)
            elif isinstance(value, str) and value.strip() == "":
                # 删除空字符串
                del obj[key]
    elif isinstance(obj, list):
        # 遍历列表的元素
        for item in obj:
            if isinstance(item, (dict, list)):
                # 递归处理嵌套对象
                clean_nested_objects(item)
            elif isinstance(item, str) and item.strip() == "":
                # 删除空字符串
                obj.remove(item)
