思路是，先将需要添加为新的列存储到一个暂时的列表中，然后用到以下函数来存储

data_.loc[:, "新列的名字"] = save_list_

上面的save_list_就是暂时存储了信息的列表了。

以下是我的代码，供以后快速回忆。

schools_data = {"985": ["北京师范大学","厦门大学","华东师范大学","中国科学院大学"],"211": ["东北师范大学","上海外国语大学","中央民族大学","华南师范大学","湖南师范大学","华中师范大学","陕西师范大学"],"一本": ["苏州大学","天津师范大学","深圳大学","首都师范大学","湖南科技大学","广东工业大学","暨南大学","宁波大学","郑州大学","河海大学","长沙理工大学","四川师范大学","广西师范大学","江西师范大学","吉林师范大学","广州大学","北京语言大学","南华大学","辽宁大学","南通大学","西北大学","武汉体育学院"],"二本": ["广东技术师范大学","广东石油化工学院","广州体育学院","星海音乐学院","广州应用科技学院","长沙师范学院","南宁师范大学","西华师范大学","首都体育学院"],"港澳": ["香港大学","香港中文大学","香港城市大学","香港理工大学","香港岭南大学"],"国外": ["哥伦比亚大学","伦敦大学学院（UCL）","悉尼大学","墨尔本大学","南安普顿大学","宁波诺丁汉大学"]
