[PyQt] [Solved]Help Getting Started on Scene Swapping

[Extra]

It worked!
Thanks for all the help, I really appreciate it.

I Just had to change:

self.win = Ui_MainDisplay.Ui_MainDisplay()

To:

      self.win = Ui_MainDisplay()

In order to get it to function properly.

I have two more questions (last ones, I promise :)

1) In my AdminMenu I am trying to have it return to the LoginScreen if the Logout buttin is clicked.
I have this:

from LoginScreen import Ui_Loginscreen
    #Logout
    def LogoutClicked(self):
        #Print in terminal for testing:
        print("The Logout Button was clicked")
        #Switch from this screen to the LoginScreen
        #Scene Swap:
        self.win = Ui_Loginscreen()
        self.win.show()
        self.close()

But I get:

Error:
 from AdminMenu import Ui_MainDisplay
ImportError: cannot import name 'Ui_MainDisplay' from partially initialized module 'AdminMenu' (most likely due to a circular import)

Is there a way to return to the previous screen or not do a circular import?

2) This is a quick side question:

I do: pyuic5 -x {The ui file.ui -> Just drag the ui file into the terminal & it will make the path} -o {output py file.py -> drag the ui file into the terminal and rename it to .py}
to convert my UI file to a Py file. When it does that conversion it uses Object instead of QMainWindow. I'm wondering if there's a way/software that can convert it from Object to QMainWindow, or do you just have to do it by hand?

Just wondering for future reference.

Thanks.
