另一种方法是使用signal.pthread_kill发送一个停止信号。

from signal import pthread_kill, SIGTSTP
from threading import Thread
from itertools import count
from time import sleep

def target():
    for num in count():
        print(num)
        sleep(1)

thread = Thread(target=target)
thread.start()
sleep(5)
pthread_kill(thread.ident, SIGTSTP)

结果

0

4

[14]+  Stopped

如果您试图终止整个程序，您可以将线程设置为“守护进程”。看到 Thread.daemon

最简单的方法是:

from threading import Thread
from time import sleep

def do_something():
    global thread_work
    while thread_work:
        print('doing something')
        sleep(5)
    print('Thread stopped')

thread_work = True
Thread(target=do_something).start()
sleep(5)
thread_work = False

你不应该在没有与线程合作的情况下强行终止线程。

杀死一个线程消除了try/finally阻塞设置的任何保证，所以你可能会让锁锁定，文件打开等等。

唯一可以认为强制终止线程是一个好主意的情况是快速终止程序，但绝不是单个线程。

正如@Kozyarchuk的回答中提到的，安装跟踪工作。由于这个答案不包含代码，下面是一个工作就绪的示例:

import sys, threading, time 

class TraceThread(threading.Thread): 
    def __init__(self, *args, **keywords): 
        threading.Thread.__init__(self, *args, **keywords) 
        self.killed = False
    def start(self): 
        self._run = self.run 
        self.run = self.settrace_and_run
        threading.Thread.start(self) 
    def settrace_and_run(self): 
        sys.settrace(self.globaltrace) 
        self._run()
    def globaltrace(self, frame, event, arg): 
        return self.localtrace if event == 'call' else None
    def localtrace(self, frame, event, arg): 
        if self.killed and event == 'line': 
            raise SystemExit() 
        return self.localtrace 

def f(): 
    while True: 
        print('1') 
        time.sleep(2)
        print('2') 
        time.sleep(2)
        print('3') 
        time.sleep(2)

t = TraceThread(target=f) 
t.start() 
time.sleep(2.5) 
t.killed = True

它在输出1和2之后停止。3不打印。

另一种方法是使用signal.pthread_kill发送一个停止信号。

from signal import pthread_kill, SIGTSTP
from threading import Thread
from itertools import count
from time import sleep

def target():
    for num in count():
        print(num)
        sleep(1)

thread = Thread(target=target)
thread.start()
sleep(5)
pthread_kill(thread.ident, SIGTSTP)

结果

0
1
2
3
4

[14]+  Stopped
