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

[metulburr]

Without passing as a parameter... i would say to create your Groot within setup directly and pass that back to the main program then. Often you will have a settings file with static data that you import to many modules. You should be cautious to use globals so often.

setup.py

# MODULE "setup.py" in moduletest
import tkinter as tk

Groot = tk.Tk()
 
def setup():
    # Create and load the display label into the window
    prompt = '        Press any key        '
    Glabel1 = tk.Label(Groot, text=prompt, width=len(prompt), bg='yellow')
    Glabel1.pack()
    return Groot

main program

import setup #<- imports go at top
...
#Groot = tk.Tk()  # Create the GLOBAL root window
Glabel1 = []     # Global Label identifier
GCOUNT = 0       # Global Keystroke counter
 

# Create and load the display label
Groot = setup.setup()
...
