[Tkinter] Tkinter - I have problem after import varaible or function from aGUI to script

[johnjh]

I have GUI Tkinter code as aGUI.py :

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

import os from tkinter import * from tkinter import ttk   root = Tk() root.title("APP") scripte = ttk.Button(root, text="Run") scripte.grid(row=3, column=2, columnspan=2, padx=20, pady=20)   db = 6     #this varaible export to script called a.py   def runApp():         print('app running')   scripte.config(command=runApp)    root.mainloop()

-------------
script code as a.py

1 2 3 4 5

from aGUI import db   number = db   print(number)

After Open App from aGUI.py and click in Run button to print db varaible from a.py , this button open app why?

--------------

After Run a.py the app from aGUI.py opened why?

Any suggested.

When you import a module it is executed. A common way to avoid this is:

1 2	if __name__ == '__main__':     # Put code you don't want to execute when imported here

You could rewrite your script to look like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

db = 6     #this varaible export to script called a.py   if __name__ == '__main__':     import os     from tkinter import *     from tkinter import ttk            root = Tk()     root.title("APP")     scripte = ttk.Button(root, text="Run")     scripte.grid(row=3, column=2, columnspan=2, padx=20, pady=20)                   def runApp():             print('app running')            scripte.config(command=runApp)            root.mainloop()

But it is more common to write it like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

import os from tkinter import * from tkinter import ttk        db = 6     #this varaible export to script called a.py   def runApp():         print('app running')        def make_panel(title):     root = Tk()     root.title(title)     scripte = ttk.Button(root, text="Run")     scripte.grid(row=3, column=2, columnspan=2, padx=20, pady=20)     scripte.config(command=runApp)        if __name__ == '__main__':     make_panel('APP')     root.mainloop()
