首先先放出我的第一个使用Pygame写的程序“菜虚鲲大战蔡徐坤”。

我在学习python的时候，学习的方向以及顺序都跟去年学习C++差不多，大致就是先从输入输出开始，然后是基本的语句，字典、列表、元组等等，然后是文件输入输出以及类与对象、继承多态等等。
这其中有很多知识我都是早早学完了，python我在去年就把基础的知识学的差不多了，Scott自学python——字符串学习笔记_轩Scott的博客-CSDN博客
Scott自学python——字典学习笔记_轩Scott的博客-CSDN博客
Scott自学python——元组学习笔记_轩Scott的博客-CSDN博客
Scott自学python——列表学习笔记_轩Scott的博客-CSDN博客
这些都是我以前学习python的博客笔记。
暑假期间我主要是学习了pygame和python的文件输入输出以及类与对象、继承多态等等，以下是我在练习中写的核酸检测登记系统

现在我们有一组从2006年到2016年1000部最流行的电影数据，
数据来源:https://www.kaggle.com/damianpanek/sunday-eda/data
（数据是本文件下的 IMDB-Movie-Data）
·问题1:我们想知道这些电影数据中评分的平均分，导演的人数等信息，我们应该怎么获
取?
·问题2∶对于这一组电影数据，如果我们想rating，runtime的分布情况，应该如何呈现数
据?
·问题3∶对于这一组电影数据，如果我们希望统计电影分类(genre)的情况，应该如何处理数据?
问题1
