how to kill a python thread under certain conditions

Question

I am trying to start a thread using python threading module. I want to kill this newly created thread under certain conditions. I have written below code snippet but this seems to hang and process never returns

from threading import Thread
import time
import os, signal
def sum():
    print("ada")
    time.sleep(5)
    print("ada1")

current = Thread(target=sum)
current.start()
current.join()
cur_pid = os.getpid()
print(cur_pid)
os.kill(cur_pid, signal.SIGSTOP)
print(current)

Do you want to kill the newly created process or the program itself? — SteapStepper69, Mar 25 '20 at 09:06

You'll want to send SIGKILL or SIGTERM, not SIGSTOP.

SIGSTOP pauses the process (which sounds like what you're seeing).

Problem is SIGKILL terminates the whole script. my last code line is never executed. I only want to kill this particular thread which is calling function – Sumit Mar 25 '20 at 09:12
With os.getpid() he is getting the PID of the actual program that created the thread, he is stopping the program instead of the thread – SteapStepper69 Mar 25 '20 at 09:13
