用户提供输入后代码未运行的问题

Question

我现在是编码的第一年。我正在为我目前遇到一些问题的学校编写程序。任务是使用文件创建一个琐事游戏。在我要求用户输入以确定他们被问的问题的价值后，我的代码将不会继续。有问题的代码部分直接贴在下面。我的整个程序都低于该程序，以防万一任何人需要查看整个程序。只是为了记录整个程序还没有完成。

P.S 我是新手，所以如果我遗漏了一些明显的东西，我深表歉意。

while repeat3==True:
    #identifying what point value the player wants        
    print "what point value do you want the question to have?"
    print "your options are:200,400,600,800,1000"
    desiredValue=input()
    print 'testing'
    if desiredValue==200:
        questionValue=random.randint(1,5)
        repeat3=False
    elif desiredValue==400:
        repeat3=False
        questionValue=random.randint(5,9)
    elif desiredValue==600:
        repeat3=False
        questionValue=random.randint(8,13)
    elif desiredValue==800:
        repeat3=False
        questionValue=random.randint(13,17)
    elif desiredValue==1000:
        repeat3=False
        questionValue=random.randint(17,20)
    else:
        print 'please entre one of the good values'
#asking the user the question        
print "Here is the question:"
print temporaryQuestions[currentCategory][questionValue]

这是我到目前为止的整个程序

对于 Python2，输入 () 可能不起作用。如果是这种情况，请使用 raw_input()。其次，输入是一个字符串，但您正在将它与一个整数进行比较。 （1 是 0+1 或 2-1，但“1”是一根棍子，“2”是看起来像向左游动的天鹅的像素负载。您可以将其与“200”进行比较或比较 int(desired_value) 200。 此外，您可能想查看 switch(),case,default 或者，因为代码在每种情况下几乎相同，所以最小/最大值的关联数组：

randMinMax = {200: {1,5}, 400: {5,9} ...}
while True:         #infinite loop - see 'break' below
    desired_input = int(raw_input)    #Might want to try/catch in case of bad input
    if desired_input in randMinMax:
        questionValue=random.randint(randMinMax [desired_input][0], randMinMax [desired_input][0])
        break;          # Break out of loop
    else:
        print 'please entre one of the good values'

但是，在这种情况下还有一个更快的版本，因为输入值和随机限制之间存在固定关系，因此：

limit = (desired_input / 200) - 1     # 0 to 4 inclusive
if limit==int(limit) and limit < 5:   # not, for example, 215
    limit = (limit * 4) + 1           # 1, 5, 9, 13, 17
    questionValue=random.randint(limit,math.min (limit+4, 20))   # Because the last limit is 20, not 21 - hence math.min
    break;                            # Got a result, stop looping.

比您要求的要多一点，但这些原则应该可以帮助您学习编码。祝你好运，尽情享受！
