      8. 个人学期总结
    2. Python是一种面向对象的解释型计算机程序设计语言，Python是纯粹的自由软件， 源代码和解释器CPython遵循 GPL(GNU General Public License)协议。Python语法简洁清晰，特色之一是强制用空白符(white space)作为语句缩进。Flask是一个面向简单需求小型应用的“微框架（microframework）”，Flask选择组件的额外工作给那些使用案例不适用标准ORM的开发者提供了更多的灵活性，同样也给使用不同工作流和模版化系统的开发者们带来了灵活性。MySQL是一个关系型数据库管理系统，MySQL 是最流行的关系型数据库管理系统之一，在 WEB 应用方面，MySQL是最好的 RDBMS (Relational Database Management System，关系数据库管理系统) 应用软件。MySQL是一种关系数据库管理系统，关系数据库将数据保存在不同的表中，而不是将所有数据放在一个大仓库内，这样就增加了速度并提高了灵活性。MySQL所使用的 SQL 语言是用于访问数据库的最常用标准化语言。
