如何在python

Question

我正在通过Zed Shaw的艰苦学习Python，并且作为练习之一，我们被要求创建一个游戏。我想创建一个押韵的游戏，打印出一个单词，玩家有5秒的时间猜出一个与打印出来的单词押韵的单词。

我能够在没有计时器的情况下让游戏工作。但是，我无法弄清楚如何使计时器与游戏同时运行。以下是代码：

#libraries
libs = [about, cake, chart, score]
#points 
p = 0
#timer
class countdown(object):

    def __init__(self, timer):
        self.timer = timer

        while timer != 0:

            print "timer: %i" % timer
            sleep(1)
            timer -= 1

        else:
            exit("You ran out of time!")

class engine(object):
    # randomly select a library    
    i = randint(0, len(libs)-1)

    randlib = libs[i].words.split(' ')     

    rhymeword = sample(randlib, 1)

    print rhymeword
    guess = raw_input("> ")

    while guess not in randlib:

        print rhymeword
        guess = raw_input("> ")

    else:
        # to reset the timer    
        timer = 5
        # points assignment
        if guess in libs[i].onesyl.split(' '):
            p += 1
            print "Points: %s" % p
        elif guess in libs[i].twosyl.split(' '):
            p += 2
            print "Points: %s" % p
        elif guess in libs[i].threesyl.split(' '):
            p += + 3
        print "Points: %s" % p

t = countdown(5)
e = engine()

t.start()
e.start()

我想做的是在用户尝试猜测时让计时器倒计时，然后在输入正确的答案后重新启动计时器。

我在python文档中研究了多处理，但我不确定如何使用它。

真的这是糟糕的设计，如果你想要这样的计时器，你应该看看gui或至少诅咒...你的输出可能不会看起来你希望

所有这些说我猜这大致是你想要的行为

import sys,time,threading

def wait_for_secs(N):
    for i in range(N):
        print N-i
        time.sleep(1)
    print "OUT OF TIME!!!"
    sys.exit(1)

threading.Thread(target=wait_for_secs,args=(15,)).start()
answer = raw_input("5+6*3=? >")
print "You Answered:",answer
sys.exit(0)

您可以使用标准模块信号制作一个简单的计时器。 这是一个例子：

import signal, sys

def handler(signum, frame):
    #print 'Signal handler called with signal', signum
    print "You ran out of time!"
    sys.exit()


def engine():    
    guess = raw_input("> ")
    print "fast enough to input",guess

# Set the signal handler and a 5-second alarm
signal.signal(signal.SIGALRM, handler)
signal.alarm(5)

engine()

signal.alarm(0)          # Disable the alarm
