想不去学习数据库支持，边试了Flask-SQLALchemy等工具，但发现那样根本不是解决办法，最后还是狠下心学数据库支持。我选择的是比较轻量级的数据库SQLite作为入门。

SQLite是一个进程内的库，实现了自给自足的、无服务器的、零配置的、事务性的 SQL 数据库引擎。它是一个零配置的数据库，这意味着与其他数据库一样，您不需要在系统中配置。

按照w3cschool提供的教程研究了一番，基本顺利。但等研究python接口的时候出现了点问题。

Even winter, there still have enough dead plants to feed.

  1. Some universities require student to take classes in many subjects. Other universities require students to specialize in one subject. Which is better?

  • Mind:  learning more than one subject at one time can expand students’ outlook, can let them see the big picture easily.( or the exploration of a wide range of subjects can expand students’ mind).

  • Effective : learning more subject at one time can save students time.

由于学校的项目，入手一台树莓派玩耍。但第一步设置时候就麻烦了，因为我的状态几本不符合网上那些教程。就配置固定IP花了近3小时。为了不让后人走弯路，我整理一下流程。

我的情况：

  1. 没有显示器。
  2. 路由器不能插网线，只能无线。
  3. 学校的网线直接插上去的话，没办法通过后台查询树莓派的IP。
