    app.run()

 

运行结果:

遇到的问题:

1、解决有道翻译返回 {'errorCode': 50}的问题:

1)更改请求 url,把translate_o修改成translate

2)参考:https://blog.csdn.net/suixinlun/article/details/93976400

2、tkinter的基本操作:

3.图形界面打包

1)使用pyinstaller来进行打包,工具安装命令:

pip install pyinstaller

2)打包命令:(只需编译入口文件即可,即:pyinstaller 选项 Python 源文件)

pyinstaller -F -w main.py
