How to get all applications/windows in the current workspace in the view of the user programmatically (in python)

Question

Let's say I have applications A, B, C in the current workspace. A and B are beside each other (assume Application A is on focus) and C is not visible on the screen (it may [minimized] or [not be minimized, but it's not visible]) . I would like the program to print A, B and not C.

I tried using the Wnck package, but I only managed to get the following:

1. Application in focus: screen.get_active_window().
2. All applications in the workspace: screen.get_windows().

but I am not able to get the application only in the view of the user, i.e. A and B.

In summary, I want to print all applications in the view of the user (which is visible on the screen), irrespective of whether they are in focus or not.

You could do something like this:

import gi
gi.require_version('Wnck', '3.0')
from gi.repository import Wnck
def get_winlist():
    """
    Get the window list and the active workspace.
    """
    scr = Wnck.Screen.get_default()
    scr.force_update()
    windows = scr.get_windows()
    active_wspace = scr.get_active_workspace()
return windows, active_wspace


wlist, active_wspace = get_winlist()
for w in wlist:
    if w.is_visible_on_workspace(active_wspace):
        print(w.get_name())

I tweaked the code I found in this answer: How to determine if window is maximised or minimised from bash script

The get_winlist() function returns a list of all open windows and the current workspace. The code after it prints only the non-minimized windows of the current workspace.
