Is this way of handling a module correct?

[9acca9]

I made a module to manage the menus of an lcd display.

The number of options is quite large so I plan to use this file as a module to import into a file that integrates other issues.

And my question goes this way. For example, when I select to log in to a page in the menu, what I do in the menu is put a variable that when entering that option becomes true.

So in the main file I have something like:

import menus

ShowMenu = menus.displayMenu(initial_menu)
ShowMenu.start()

while 1:
    if ShowMenu.login == True:
        makesomething
        ShowMenu.login = False
    if.... etc.

This is well? I mean, interact in this way with the other module? have a variable in the menus module that help me organize the main flow?
