Python：繼續從一個點循環

我剛剛開始了一門Python編程課程，並試圖一步一步來。我只是爲自己創建了一點西班牙語 - 英語提醒，現在我正面臨着一個diufficulty。我用英語問一個問題，需要用西班牙語翻譯..如果答案是正確的，我可以繼續，但如果答案是錯誤的，我想再次問qeustion ..這是我的代碼到目前爲止，我的問題如果我給出了錯誤的答案，循環回到第一個問題..你能幫我什麼，我應該添加只是爲了重複我沒有正確回答的問題？Python：繼續從一個點循環

謝謝你，

while True: 
    ask = raw_input('How are you? ') 
    answer = str(ask) 
    if answer == 'Que tal?': 
     ask = raw_input(' Sorry, I have other programs ') 
     answer = str(ask) 
    if answer == 'Lo siento, pero ya tengo otros planes': 
     ask = raw_input(' I am reading a book ') 
     answer = str(ask) 
    else: 
     continue

看起來你需要使用多個循環。我會爲每個問題使用一個循環，當您想要移動到下一個問題時使用「break」。 – Sam 2015-03-02 08:13:45

創建的questions及其answers列表。將這些細節保存在任何變量中名單。
使用for loop可迭代問題列表項並使用raw_input()提問。
檢查用戶答案是否正確通過if condition。
如果用戶回答錯誤，則再次向用戶提出同樣的問題。
如果用戶回答正確，則詢問下一個問題。使用break聲明從while循環中出來。

限制： 如果用戶沒有給出正確回答任何問題，然後程序會一次又一次地問同一個問題，直到用戶給出正確的答案。

演示：

#- Create List of tuples which contains question and respective answer.  
questions = [("Question number one?", "one"), ("Question number two?", "two"),\ 
      ("Question number three?", "three")] 

for i in questions: 
    while 1: 
     ans = raw_input(i[0]) 
     if ans==i[1]: 
      print "Correct." 
      break 
     else: 
      print "Wrong answer"

輸出：

[email protected]:~/workspace/vtestproject$ 
[email protected]:~/workspace/vtestproject$ python task4.py 
Question number one?test1 
Wrong answer 
Question number one?test1 
Wrong answer 
Question number one?one 
Correct. 
Question number two?two 
Correct. 
Question number three?test3 
Wrong answer 
Question number three?three 
Correct.

演示：

#- Create List of tuples which contains question. optinons and respective answer. 
questions = [("Question number one?", ["a. one", "b. two", "c. three"], "a"),\ 
      ("Question number two?", ["a. one", "b. two", "c. three"], "b"),\ 
      ("Question number three?", ["a. one", "b. two", "c. three"], "c") 
      ] 

#- Set number of chances to solve each question. 
chances = 3 
#- Score. Plus one for each correct answer. 
score = 0 

for i in questions: 
    print "-"*10 
    for j in xrange(0, chances): 
     print "Question:", i[0], "\n Options:", i[1] 
     ans = raw_input("Enter option:") 
     if ans==i[2]: 
      print "Correct." 
      score += 1 
      break 
     else: 
      print "Wrong answer" 


print "Your score: ", score

輸出：

----------

Enter option:c 
Wrong answer 
Question: Question number one?

Enter option:c 
Correct. 
Your score: 2
