Question

好的。因此，這是我迄今爲止.... #Russian翻譯課程

import os 
import random 

#Asks users if they want to add more vocabulary 
word_adder=raw_input("Add more words? If yes, press 1: ") 
with open("Russian_study.txt","a") as f: 
    while word_adder=="1": 
     word=raw_input("Enter word: ") 
     translation=raw_input("Word translation: ") 
     f.write("{0}:{1},/n".format(word,translation)) 
     word_adder=raw_input("Add another word? If yes, press 1: ") 

#Checks to see if file exists, if not one is created 
with open("Russian_study.txt","a") as f: 
    pass 

os.system('clear') 
print("Begin Quiz") 

#Begin testing user 
with open("Russian_study.txt","r") as f: 
    from random import choice 
    question, answer = choice(list(f)).split(':') 
    result = raw_input('{0} is '.format(question)) 
    print('Correct' if result==answer else ':(') 

這個程序工作，但是，當添加多個條目總是顯示不正確的。任何幫助？此外，它在一個問題後停止運行，從未進入下一個問題....

Answer 1

這裏有幾個問題。

1. 一個錯字：的\n/n代替f.write("{0}:{1},/n"...

2. 當你做list(f)首次在循環中，它調用f.readlines()這將讀「指針」文件的末尾。因此，所有後續調用list(f)將返回一個空列表。謹防這種隱藏的狀態。

3. list(f)在它返回的行中包含換行符號，再加上任何回答結尾的逗號。所以answer得到像"word,\n"。在比較answer和result之前，必須去掉這兩個字符。

4. 在第一個問題後停止運行，因爲您在提問部分沒有循環。

5. 另外，Python3中沒有raw_input，只是input。

有了這一切記住，固定程序（最小的變化）可能看起來像：爲我工作

import os 
import random 

#Asks users if they want to add more vocabulary 
word_adder=input("Add more words? If yes, press 1: ") 
with open("Russian_study.txt","a") as f: 
    while word_adder=="1": 
     word=input("Enter word: ") 
     translation=input("Word translation: ") 
     f.write("{0}:{1},\n".format(word,translation)) 
     word_adder=input("Add another word? If yes, press 1: ") 

#Checks to see if file exists, if not one is created 
with open("Russian_study.txt","a") as f: 
    pass 

os.system('clear') 
print("Begin Quiz") 

#Begin testing user 
with open("Russian_study.txt","r") as f: 
    l = list(f) 
    from random import choice 
    while True: 
     question, answer = choice(l).split(':') 
     answer = answer[:-2] 
     result = input('{0} is '.format(question)) 
     print('Correct' if result==answer else ':(')

代碼。感謝所有幫助傢伙
