Python 翻译程序

嗯。这就是我到目前为止得到的#俄语翻译程序

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 ':(')

但是，当添加多个条目时，该程序始终显示不正确。有什么帮助吗？此外，它会在一个问题后停止运行，永远不会进入下一个问题。…

这里有几个问题

打字错误：

/n

而不是

\n

在

f.write（“{0}:{1}，/n”…

当您第一次在循环中执行

list（f）

时，它会调用

f.readlines（）

，这会将读取的“指针”移动到文件的末尾。因此所有后续调用

list（f）

都将返回空列表。请注意此隐藏状态

list（f）

在返回的行中包含换行符，并且在任何答案的末尾都有一个逗号。因此

answer

得到类似

“word\n”

。在将

answer

与

result

进行比较之前，必须去掉这两个字符

它在第一个问题之后停止运行，因为在提问部分没有循环

另外，Python3中没有

原始输入

，只有

输入

考虑到所有这些因素，固定程序（变化最小）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 ':( ')

对我有用的代码。谢谢大家的帮助

导入操作系统 随机输入

#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:
    l = list(f)
    from random import choice
    while True:
        question, answer = choice(l).split(':')
        answer = answer[:-2]
        result = raw_input('{0} is '.format(question))
        print('Correct' if result==answer else ':( ')

哈，你刚刚抢先一步。输入不起作用。它只在使用原始输入时运行。这很奇怪。我安装了Python 3.3.1，没有

raw\u input（）

。此外，在中也没有提到

raw\u input（）

。
