如何在另一个具有不同类的python文件中使用pyqt5类中存在的函数的输出？

我使用PYQT5创建了简单的GUI，要求用户提供服务器名称。并想在另一个python unittest脚本中使用用户输入。我是python世界中的新手，正在尝试学习。我已经在psft.py中导入了test_launch.py​​文件，并尝试了以下代码：

self.obj= test_launch.Ui_MainWindow() 
self.host1=self.obj.host() 
print(self.host1)

，但是在test_launch中单击GUI lauch按钮上的启动按钮并调用执行函数并调用脚本psft.py却无法打印时，但是在psft.py中却无法打印用户输入。

您正在启动一个进程，因此使用脚本不会使您获得所需的值。

使用this answer，您可以通过环境变量传递数据
