[Tkinter] HOW TO: Use Globals In Module ???

[Webtest]

Thanks metulburr!
Your suggestion looks reasonable and your advice is sound. I did a LOT of searching, and did find MANY caveats regarding Globals. However, I did also find the following ELEGANT and sanctioned solution, which works great for my program:

Python Software Foundation
Programming FAQ: How do I share global variables across modules?

It is very brief and is well worth looking at. Basically, you just put all the Globals in a "config.py" file. That puts them all in a single file in their own namespace ... I use "import config as G", so each Global is "G.name". Without this I would be passing TONS of stuff ... 3 arrays of 65 widgets each, a dictionary of complex dynamic widget formats, and many other variables. Each of the FIVE steps of the State Machine manipulates them differently.

# Module config.py
Root = []       # Global Window identifier
Label1 = []     # Global Label identifier
Count = 0       # Global Keystroke counter

# Module Test for Globals and Modules
import tkinter as tk
import config as G
import setup
 
G.Root = tk.Tk()  # Create the GLOBAL root window

# Create and load the display label
setup.setup()
 
# #########  Keyboard 'Keypress' event handler  #########
def key(event):
    G.COUNT += 1
    msg = '%d %r %d %d' %(G.COUNT,event.keysym,event.keysym_num,event.state)
    print(msg)
# #######################################################
 
# Bind the Keypress event to the 'key' event handler
G.Root.bind_all('<Key>', key)
# Exit to the running event-driven app
G.Root.mainloop()

# MODULE "setup.py" in moduletest
import tkinter as tk
import config as G
 
def setup():
    # Create and load the display label into the window
    prompt = '        Press any key        '
    G.Label1 = tk.Label(G.Root, text=prompt, width=len(prompt), bg='yellow')
    G.Label1.pack()   #  <-- pack/grid MUST be on separate line !!!
    return

Blessings in abundance, all the best, & ENJOY!
