教材学习内容总结

阅读《计算机科学概论》第9章（面向对象设计与高级程序语言设计），了解了面向对象方法，翻译过程及其工具，两种程序设计语言范型，高级程序设计语言和面向对象语言的功能性等内容，并学习了过程设计和面向对象设计的区别。
阅读《看漫画学Python》第9、10章（类与对象、异常处理），了解了面向对象、定义类、创建对象、类的成员、封装性、继承性、多态性、除零异常、捕获异常、finally代码块、自定义异常等内容。

教材学习中的问题和解决过程

本周暂无

代码调试过程中的问题和解决过程

问题1：有一个代码照着书打，没有发现问题，但结果无法运行出来
问题1解决方案：在云班课上与同学讨论，得知是缩进出了问题，修改后就可以正常运行了。
问题2:9.7.2最后一个代码打完后正常运行但是不输出结果
问题2解决方案：经过对比教材和我的代码，发现我漏打了一个括号，导致没有引用
