Pass value from class_1 to class_2

[hobbyist]

I use PyQt5. I have a GUI with menus. So when I press menu_1 it runs class_1 and produces a value, value_1. When I choose menu_2 it runs class_2 and I want to pass the value_1 to class_2 , So that value_2 = value_1 . class_1 is stored in different file than class_2 . How can I achieve that?

Can you please give me an example with signals/slots?

Qt documentation provides many examples

Something irrelevant...PyQt5 and PySide6 are open source code, right?
