encounters the same problem, the while True in the method called by the
thread cannot jump out of the thread ending the while loop outside the while

def startsendfile(self,filelist,taskpath,filetypepath):

    for k in range(2):
        -sharp new_thread = threading.Thread(target=self.booth(k,filelist,taskpath,filetypepath))
        new_thread = threading.Thread(target=self.booth,args=(k,filelist,taskpath,filetypepath))

    for t in self.thread_list:
        t.start()
    for t in self.thread_list:
        t.join()
    print("", time_now())

Thread calls methods

def booth(self,tid, filelist,taskpath,filetypepath):
    global thread_data_num
    global lock
    while True:
        self.lock.acquire()
        print(self.thread_data_num)
        if self.thread_data_num != 0:
            self.thread_data_num = self.thread_data_num - 1
            item = filelist[self.thread_data_num]
            time.sleep(10)
        else:
            break
        self.lock.release()
    print("")
    

is the result printed = > is it out

but does not print = > all threads end
