需要的环境为python3.6、pyqt5（建议直接安装Anaconda，因为安好python后自带pyqt5），还有QTcreator（用来写ui界面），还需要一个编辑器（sublime或者notepad++均可，我使用的是PyCharm，毕竟IDE用起来顺手）。使用到的工具就是如下图：
- 1、先做个ui界面
打开QT，新建一个项目，打开设计界面，可以看到很多控件直接可以拖拽到右面的界面上，在编辑界面中可以看到直接生成了ui代码。
![《PYQT5+python3.6+QT编写一个带ui的加密解密小程序》]()
上图是需要完成的ui，拖拽一下就可以完成
要注意在右侧对各个控件命好名字，能自己区分（请无视我的命名方法= =），后期函数调用时需要用到
完成后到项目所在目录下找到mainwindow.ui文件
在cmd中打开当前目录，使用命令将xml代码转换为python代码
pyuic5 -o a.py mainwindow.ui
- 2、打开pycharm添加其他代码
新建一个工程，在工程下建立一个包，然后会自动生成__init__.py，把上边的a.py拖入包中
代码
