kill python execution program

[lebossejames]

Dear,

I want to stop my python program by a bash script normally so i have these code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

from time import sleep import sys import os import threading from _thread import interrupt_main   from timed_count import timed_count   class MyThreadReadUpdate (threading.Thread):     def __init__(self):         threading.Thread.__init__(self)         self._running = True                        def terminate(self):         self._running = False               def run(self):         while self._running:               #print("MyThreadReadUpdate is running")              if os.path.exists(sys.argv[2]):                                      f3 = open(sys.argv[2], "r+")                 valueToDo=f3.readline().rstrip()                 #print(valueToDo+"/")                 if (valueToDo == "Close" ):                     print("Exiting program is asked by user")                                           sleep(2)                     f3.seek(0);                     f3.write("Nothing")                     f3.close()                     sys.exit(0)                   else:                     #print("run always this program")                     f3.close()             #time.sleep(5)     readUpdate_Thread = MyThreadReadUpdate() readUpdate_Thread.daemon = True    readUpdate_Thread.start()     while True:      print("loop")      sleep(3)

So my readUpdate_Thread is kill not my main Thread (while True) .

Thank you for your answers.
