I have a window that is opened up in a Python script (NOT THROUGH Tkinter), and all I want is to send an "enter" (keypress) command to that window. I was hoping I could do this with Tkinter, but I'm at a bit of a loss as to how to send this command to the current focused window.
You cannot do this with Tkinter. Tkinter can only send events to its own windows.
Tkinter keypress on current focused window
