• is there way kill thread in python? 19 answers

i did little search , found out there no way kill thread in python, how 1 solve problem me ?

i have function sets x true 1 hour , after sets false.

sometimes program finishes less needed hour, thread still running , make garbage in memory.

    def enablex():         self.x=true         sleep(3600)         self.x=false     def function1():         self.enablexthread=thread(target=self.enablex)          self.enablexthread.start() 

any idea ? how can kill enbablexthread when program terminates no matter if thread done or not ?

how can kill enbablexthread when program terminates

if thread not have cleanup do, make daemon thread setting enablexthread.daemon true. must done before starting thread:

self.enablexthread = thread(target=self.enablex)  self.enablexthread.daemon = true self.enablexthread.start() 

otherwise, use exit flag (a global variable threads check see whether should exit) or event handler.

you might considering using signal this, may simpler threading; can set alarm hour , have handler reset variable. if process ends before alarm goes off, nothing happens. note isn't available on windows.

import signal  x = false  def handle_alarm(signum, frame):     global x     x = false  signal.signal(signal.sigalrm, handle_alarm)  def set_x_true_then_false_later(secs=3600):     global x     x = true     signal.alarm(secs)
