如何“停止”和“恢复”长时间运行的Python脚本？

这很简单，希望可以对您有所帮助：

import timeimport pickleREGISTRY = Nonedef main(start=0):    """Do some heavy work ..."""    global REGISTRY    a = start    while 1:        time.sleep(1)        a += 1        print a        REGISTRY = pickle.dumps(a)if __name__ == '__main__':    print "To stop the script execution type CTRL-C"    while 1:       start = pickle.loads(REGISTRY) if REGISTRY else 0        try: main(start=start)        except KeyboardInterrupt: resume = raw_input('If you want to continue type the letter c:') if resume != 'c':     break

运行示例：

$ python test.pyTo stop the script execution type CTRL-C123^CIf you want to continue type the letter c:c456789^CIf you want to continue type the letter c:$ python test.py
