1.代码比较简单，但是代码里面 各个元素的id 和取xpath的规则 可能会因为机型不一样 而不一样。

2.因为是练习，所有就从登录微信 开始一步步操作 ，其实上 只用设置noReset 等于True ，我们就不需要每一次都登录了，还能保存数据。

3.appium/python-client使用文档https://github.com/appium/python-client

4. desired_caps 的各种参数(启动app的时候 ，各种参数配置) https://github.com/appium/appium/blob/master/docs/en/writing-running-appium/caps.md
