使用KeyboardInterrupt停止python脚本

Question

嗨，为什么我的KeyboardInterrupt:当我按下control c或control x时，没有停止我的程序？这是我当前的代码。

我使用的是python线程，它运行两个函数coinPulser和coinPulserDone。

import threading
import time

lock = threading.Lock()
counter = 0
input = 3

def coinPulser ():
    global counter
    global input
    lock.acquire()
    try:
        while counter < input:
            counter+=1
            time.sleep(.1)
            if counter in [1,3,5]:
                print(counter)
        return counter
    finally:
        lock.release()

def coinPulserDone ():
    while True:
        print(coinPulser())


try:
    coinpulser = threading.Thread(target = coinPulser)
    coinpulser.start()
    coinpulserdone = threading.Thread(target = coinPulserDone)
    coinpulserdone.start()
except KeyboardInterrupt:
    coinpulser.stop()
    coinpulserdone.stop()
    print('Thread Stops')

我怀疑问题在于您的代码在按Cntr C组合键之前退出了try/except块。您需要添加某种形式的循环，以将其保存在该块中。一个简单的循环，比如

while True:
    time.sleep(1)

在你的the行应该可以做这个之前。
