捕获KeyboardInterrupt并在发生暂停后恢复

Question

我尝试捕获键盘中断并在用户选择使用以下代码恢复进程后恢复：

except KeyboardInterrupt:
    q = prompt("CNTRL-C was pressed what would you like to do", "quit(q)/pause(p)")
    if q.lower().startswith("q"):
        shutdown(0)
    elif q.lower().startswith("p"):
        LOGGER.warning("Application will pause until a key is pressed..")
        try:
            os.system("pause")
        except:
            os.system("read -p")
    else:
        shutdown(0) # shut down is just exit with a log message

然而，似乎每当我按下键继续后我尝试这样做时，它就会退出该过程：

[*] Starting up at: 1498843527.18..

[12:25:27 INFO] Using algorithm, MSSQL 2000..
[12:25:27 PROMPT] CNTRL-C was pressed what would you like to do[quit(q)/pause(p)]: p
[12:25:28 WARNING] Application will pause until a key is pressed..
Press any key to continue . . .

如何让程序记住我在做什么，然后在用户决定之后恢复相同的过程？
