Stopping a python thread running an Infinite Loop

Question

I am new to python programming. I am trying to make a GUI with stoppable threads. I borrowed some code from https://stackoverflow.com/a/325528

class MyThre         


        

Answer 1

I think you missed the 'The thread itself has to check regularly for the stopped() condition' bit of that documentation.

Your thread needs to run like this:

while not self.stopped():
    # do stuff

rather than while true. Note that it is still only going to exit at the 'start' of a loop, when it checks the condition. If whatever is in that loop is long-running, that may cause unexpected delays.

Answer 2

import threading
import time
class MultiThreading:

    def __init__(self):
        self.thread = None
        self.started = True
    def threaded_program(self):
        while self.started:
            print("running")
            # time.sleep(10)
    def run(self):
        self.thread = threading.Thread(target=self.threaded_program, args=())
        self.thread.start()
    def stop(self):
        self.started = False
        self.thread.join()
