这里还有另一种方法，但代码非常干净和简单，适用于2021年的Python 3.7:

import ctypes 

def kill_thread(thread):
    """
    thread: a threading.Thread object
    """
    thread_id = thread.ident
    res = ctypes.pythonapi.PyThreadState_SetAsyncExc(thread_id, ctypes.py_object(SystemExit))
    if res > 1:
        ctypes.pythonapi.PyThreadState_SetAsyncExc(thread_id, 0)
        print('Exception raise failure')

改编自:https://www.geeksforgeeks.org/python-different-ways-to-kill-a-thread/

您可以在进程中执行命令，然后使用进程id终止它。 我需要在两个线程之间同步，其中一个线程本身不返回。

processIds = []

def executeRecord(command):
    print(command)

    process = subprocess.Popen(command, stdout=subprocess.PIPE)
    processIds.append(process.pid)
    print(processIds[0])

    #Command that doesn't return by itself
    process.stdout.read().decode("utf-8")
    return;


def recordThread(command, timeOut):

    thread = Thread(target=executeRecord, args=(command,))
    thread.start()
    thread.join(timeOut)

    os.kill(processIds.pop(), signal.SIGINT)

    return;

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

我对这个游戏已经很晚了，但我一直在与一个类似的问题作斗争，下面的内容似乎为我完美地解决了这个问题，并且让我在守护子线程退出时做一些基本的线程状态检查和清理:

import threading
import time
import atexit

def do_work():

  i = 0
  @atexit.register
  def goodbye():
    print ("'CLEANLY' kill sub-thread with value: %s [THREAD: %s]" %
           (i, threading.currentThread().ident))

  while True:
    print i
    i += 1
    time.sleep(1)

t = threading.Thread(target=do_work)
t.daemon = True
t.start()

def after_timeout():
  print "KILL MAIN THREAD: %s" % threading.currentThread().ident
  raise SystemExit

threading.Timer(2, after_timeout).start()

收益率:

0
1
KILL MAIN THREAD: 140013208254208
'CLEANLY' kill sub-thread with value: 2 [THREAD: 140013674317568]

可以通过在将退出线程的线程中安装trace来终止线程。请参阅所附的链接，了解一种可能的实现。

在Python中杀死一个线程

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。
