python socket通信--Apple的学习笔记

之后，我还需要为python制作界面。就先拿我之前的一个python工具，当时做的配置信息是手工填写到settings文件中，然后调用bat后通过python生成代码。那么我就为它做个界面练练手，主要是把基本控件都用下。摸底后，感觉方案可行，ttk的API还是比较友好的。之后还需要添加treeview控件，用来进行数据实时更新。

入门学习了下tinker和ttk的基本控件后，制作界面如下，感觉布局不灵活。

如下源码功能说明：从json文件中读取原来的配置信息，然后在界面中修改原来的配置信息，通过按钮可以保存为新的配置信息。其实按钮回调函数中我再添加直接call bat文件，即可通过配置文件直接生成c代码了，和之前的工具可以无缝链接~
