[Tkinter] Return a value to __main__

[Coricoco_fr]

This is a better practice.

import tkinter as tk


class Window(tk.Frame):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.count = 1
        self.label = tk.Label(self, text='Hello World')
        self.label.pack()
        self.counter()
 
    def counter(self):
        self.label['text'] = self.count
        self.count += 1
        self.after(1000, self.counter)

if __name__ == '__main__':

    root = tk.Tk()
    bt = tk.Button(root, text="Press to stop", command=quit)
    bt.grid()
    app = Window()
    app.grid()

    root.mainloop()
