python - IF 语句不比较从文件接收的值

Question

我几天前刚刚开始编程。我制作了这个程序，用户可以在其中创建测验(所有 Q 和 A 都写入文件中)当我读取答案文件时，我使用 with 语句来独立提取每一行，然后将其与每个独立行进行比较Qs 文件的。这工作得很好，我想要比较的值确实是。但是当答案实际上与文件中的答案匹配时，if 语句仍然返回 else 命令!这太不可思议了!这是用于澄清的输出。

Question Number 1 : Whats your name

input the Answer :abdo

Sorry, thats Wrong! The right answer is : abdo

Your score is : 0

Question Number 2 : whats my name

input the Answer :abdo1

Sorry, thats Wrong! The right answer is :abdo1

Your score is : 0

这是我的代码:

import sys
questions = []
answers = []
score = 0
print("+++++++++++++++Welcome to SS Quiz Maker++++++++++++++++")
save = input("Would you like to create a new quiz or load your saved one :")
if save == "y":
    for i in range(0,2):
        print( "Question number",i + 1)
        questions.append(input("Enter a Question :"))
        answers.append(input("Enter an Answer :"))

    f = open("SS_QUIZ_QUESTIONS.txt", "w")
    f.truncate()
    for i in questions:
        f.write(i)
        f.write("\n")
    f.close()
    f = open("SS_QUIZ_ANSWERS.txt", "w")
    for i in answers:
        f.write(i)
        f.write("\n")
    f.close()
else:   
    for i in range(0,2):
        with open('SS_QUIZ_QUESTIONS.txt') as f:
            u = 1
            for line in f:
                if u == i + 1:
                    break
        with open('SS_QUIZ_ANSWERS.txt') as f:
            u = 1
            for line2 in f:
                if u == i + 1:
                    break
        print("Question Number ",i + 1," :",line)
        ans = str(input("input the Answer :" ))

        if  ans == line2:
            print("Correct")
            score = score +1
            print("Your score is :",score)

        else:
            print("Sorry, thats Wrong!")
            print("The right answer is :", line2)
            print("Your score is :",score)

Answer 1

问题是，当您将答案写入文件时，您还写入了换行符“\n”。现在，当您比较字符串时，您实际上是将 abdo1 与 abdo1\n 进行比较，这是错误的。在比较之前，对 line2 字符串使用 .rstrip() 方法。

在您的代码中:

if ans == line2.rstrip():

应该可以解决问题
