stop multiple threads

[woooee]

Here it is using multiprocessing if it helps. https://pymotw.com/3/multiprocessing/index.html

import sys
if 3 == sys.version_info[0]: ## 3.X is default if dual system
    import tkinter as tk     ## Python 3.x
else:
    import Tkinter as tk     ## Python 2.x

import time
from multiprocessing import Process

class TestClass():
    def test_f(self, spaces=1):
        ctr = spaces
        while True:
            ctr += 1
            print(" "*spaces, ctr)
            time.sleep(1.0)

    def tk_quit(self):
        root=tk.Tk()
        tk.Button(root, text="Quit", command=root.quit,
                  width=10).grid()
        root.mainloop()

if __name__ == '__main__':
     ## run functions in the background
     CT=TestClass()
     p = Process(target=CT.test_f)
     p.start()
     ## run same function in another process to 
     ## simulate 2 different processes
     p2 = Process(target=CT.test_f, args=(10,))
     p2.start()

     CT.tk_quit()
     print("terminate process")
     if p.is_alive():
         p.terminate()
         p.join()
     if p2.is_alive():
         p2.terminate()
         p2.join()
