用戶提供輸入後代碼未運行問題

Question

我在編碼的第一年。我正在編寫一個我目前遇到問題的學校計劃。該任務是使用文件創建一個瑣事遊戲。在我詢問用戶輸入以確定他們被問到的問題值多少分之後，我的代碼將不會繼續。具有問題的代碼部分直接在下面發佈。我的整個計劃都低於這個水平，以幫助任何人需要看到整個事情。只是爲了記錄整個程序尚未完成。

P.S我是新來的，所以如果我錯過了一些明顯的道歉，我很抱歉。

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]

Answer 1

對於Python2，輸入（）可能無法正常工作。如果是這種情況，請使用raw_input（）。其次，輸入是一個字符串，但你將它與一個整數進行比較。 （1是0 + 1或2-1，但是「1」是一個棒，「2」是看起來像天鵝游泳到左邊的像素的負載，可以將它比較爲「200」或比較int（desired_value）用200 此外，你可能想看看開關（），的情況下，默認爲這個或，因爲代碼是在每種情況下幾乎相同，最小/最大值的關聯數組：

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' 

然而，還有在這種情況下，一個更快的版本，因爲在輸入值和隨機限制等等之間的固定關係：

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. 

比你問但這些校長建議立即進行刪除多一點當你學習編碼時，d可以幫助你。祝你好運，享受！
