IF==不适用于python中的列表。不知道我做错了什么。数据的打印（）显示它们是相等的…我遗漏了什么？

这是我的代码。 它意味着从用户那里获取答案。 将他们的答案存储在一个列表（answerlist）中。 将他们的答案与answers.txt文件行中的列表进行比较

问题是，尽管它们是相同的（查看print（）输出），但脚本并没有将它们视为：

import time
import os

answerlist = []
check = "N"
score=0
real_answerlist=[]
checkanswerlist=[]



name = input("\nWhat is your FIRST name?\n")
surname = input("\nWhat is your SECOND/surname?\n")
classname = input("\nWhat is your class (e.g. \"8A\")\n")
while check != "Y":
    print("Are these detail correct? : "+name + " "+surname+" " + classname+"\n")
    check = input("Enter (Y or N)\n")


#ASK QUESTIONS

for i in range(1, 11):
    answerlist.insert(i,input("The answer to question "+str(i)+" is: \n"))


#show answers
for i in range (1, 5):
    print("Your answers will be shown below in "+str(5-i)+"seconds... ")
    time.sleep(1)
    os.system('cls')

for i in range(0,len(answerlist)):
    print(str(i+1)+": "+answerlist[i])

#Ask if want any answers changing?

while check != "N":
    check=input("\n Do you want to change any answers? (Y or N)\n")
    if check!="N":
        question_to_correct=input("Which question do you want to change?\n")
        corrected_answer=input("What do you want to change your answer to?\n")
        answerlist[int(question_to_correct)-1]=corrected_answer
        print("Here are your answers...")
        for i in range(0,len(answerlist)):
            print(str(i+1)+": "+answerlist[i])

#Place result in to text file:
string_to_write=",".join(answerlist)

f = open("Y8Answers.csv","a") #opens file with name of "username"
f.write("\n"+name+","+surname+","+classname+","+string_to_write)
f.close()


print("Test completed.")

#show results
for i in range (1, 3):
    print("Your answers will be shown below in "+str(5-i)+"seconds... ")
    time.sleep(1)
    os.system('cls')

p=0;
with open("answers.txt") as f:          #Shove all the real answers from answers.txt in to a list "real_answerlist".
        for line in f:
            real_answerlist.append(line)

        for i in range (0,len(answerlist)):             #if their answer == answer in list, add one to score.
            if str(answerlist[i])==str(real_answerlist[i]):
                score=score+1
                print(answerlist[i]+" "+real_answerlist[i])
            else:
                print("Question "+str(i+1)+" is incorrect."+" Your answer: "+str(answerlist[i])+" real is: "+str(real_answerlist[i]))

print (score)

“answers.txt”的内容：

当脚本运行时（在回答正确答案后），我的输出是：

谢谢你的帮助！我相信这会很简单，因为我是一个非常粗鲁的人（你可以从我糟糕的代码中看出：p）！

从文件中读取的答案有尾随的新行，打破了比较。将

real\u answerlist.append（line）

替换为

real\u answerlist.append（line.strip（））

从文件中读取的答案后面有中断比较的换行符。将

real\u answerlist.append（line）

替换为

real\u answerlist.append（line.strip（））

是谁教你读那样的文件的？@Gullydwarf-有没有更好的方法逐行阅读并将它们放入列表中？我对with语句的使用更感兴趣。我通常创建一个文件对象并使用“readLines（）“@Gullydwarf:with使用

的好处是，你不必担心在完成或出现任何异常时关闭文件，因为这将自动完成。谁教你读那样的文件？@Gullydwarf-有没有更好的方法逐行阅读并将其放入列表中？我对使用更感兴趣我通常创建一个file对象并使用'readLines（）'@Gullydwarf:with
