Python - 做一些事情直到按键或超时

Question

我几乎已经解决了这个问题，但我认为我需要朝着正确的方向插入。

我想每五秒执行一次操作，直到 已经过去了一定的时间，或者用户中断了它(在这种情况下它完成了循环的迭代在完成之前)。

import time
import threading

def do_something():
    T0 = time.clock()
    while (time.clock() - T0) < 60 and not e.isSet(): #as long as 60s haven't elapsed
                                                      #and the flag is not set
        #here do a bunch of stuff
        time.sleep(5)

thread = threading.Thread(target=do_something, args=())
thread.start()
e = threading.Event()

while thread.isAlive():
    #here I want the main thread to wait for a keypress and, if it receives it,
    #set the event e, which will cause the thread to finish its work.

我不知道如何让最后一行工作。在循环内使用 raw_input() 将阻塞，直到用户点击回车，无论线程是否完成其工作。是否有另一个模块可以满足我的要求？

编辑:我使用的是 Windows XP。

您可以使用 thread.interrupt_main() .

示例:

import thread
import time
import threading

e = threading.Event()

def main():
    thread.start_new_thread(wait_for_input, tuple())
    thread.start_new_thread(do_something, tuple())

def wait_for_input():
    raw_input()
    e.set()

def do_something():
    T0 = time.clock()
    while (time.clock() - T0) < 60 and not e.isSet(): #as long as 60s haven't elapsed
                                                      #and the flag is not set
        #here do a bunch of stuff
        time.sleep(5)
    thread.interrupt_main() # kill the raw_input thread

try:
    thread.start_new_thread(main, tuple())
    while 1:
        time.sleep(0.1) 
except KeyboardInterrupt:
    pass
