Question

确定。所以这就是我到目前为止...... #Russian Translation Program

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 ':(')

此程序有效，但是当添加多个条目时，它始终显示不正确。有帮助吗？此外，它在一个问题后停止运行，永远不会到达下一个问题....

Answer 1

这里有几个问题。

1. /n

中的拼写错误：\n而不是f.write("{0}:{1},/n"...

2. 当您第一次在循环中执行list(f)时，它会调用f.readlines()，将读数“指针”移动到文件的末尾。因此，对list(f)的所有后续调用都将返回一个空列表。小心这个隐藏的状态。

3. list(f)在其返回的行中包含换行符号，并且在任何答案结尾处都有逗号。因此answer会得到类似"word,\n"的内容。在将answer与result进行比较之前，您必须删除这两个字符。

4. 在第一个问题之后停止运行，因为你在提问部分没有循环。

5. 此外，Python3中没有raw_input，只有input。

考虑到所有这些，固定程序（变化很小）可能如下所示：

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 ':( ')

适用于我的代码。感谢所有帮助人员
