如何使列表中的項目顯示，並且來自用戶的輸入

Question

是否可以使列表中的項目一次顯示一個項目，但是在程序顯示下一個項目之前它必須等待用戶輸入？

這裏是我的代碼：

import os 

correct=0 
incorrect=0 
missed_questions=[] 
incorrect_questions=[] 

def question1(question_name,question): 
    print(question_name) 
    print(question) 
    answer=int(input()) 
    if answer == 4: 
     os.system('cls') 
     global correct 
     correct=correct+1 
    elif answer != 4: 
     global incorrect 
     incorrect=incorrect+1 
     global missed_questions 
     missed_questions.append(question_name) 
     global incorrect_questions 
     incorrect_questions.append(question)

     incorrect=incorrect+1

我試圖在重走funcation列表。

Answer 1

你可以這樣做：

a = ["first answer", "second answer", "last answer"] 
answer = raw_input("\n".join([chr(x + ord('A')) + ") " + a[x] for x in xrange(len(a))])) 

（對於Python 3）編輯：

a = ["first answer", "second answer", "last answer"] 
answer = input("\n".join([chr(x + ord('A')) + ") " + a[x] for x in range(len(a))])) 

說明：個

for x in xrange(len(a)) 

遍歷列表a

chr(x + ord('A')) 

的索引的索引轉換成字母 - 0-> A，1-> B，2->Ç

chr(x + ord('A')) + ") " + a[x] 

格式化包含答案字母和答案本身的字符串。

A）第一個答案
B）第二應答
C）最後的回答

每一個seperatedly。

[chr(x + ord('A')) + ") " + a[x] for x in xrange(len(a))] 

生成經過格式化的回答字符串（迭代的列表，格式的字符串，並將其轉儲到一個列表。
現在，

"\n".join[chr(x + ord('A')) + ") " + a[x] for x in xrange(len(a))] 

注意到該清單，並與\n串接它s。現在剩下的一切就是打印它並等待一個答案
希望我幫助

Answer 2

看到這個：

l = [1, 2, 3] # Your list 
for i in l: 
input = raw_input("Show message") # Get input before 
print "current list item ", i  # displaying list item
