Question

我在Python中进行了一个简单的测验，但遇到了问题。它以“问题，答案”格式读取逗号分隔的文本文件。该程序正在仔细阅读测验并输出问题，但我无法将问题随机化，也无法通过“ CorrectAnswer”变量来获取正确答案。

例如，如果问题是“加利福尼亚的首都在哪里？”答案是“萨克拉曼多”，则CSV文件的格式如下：“加利福尼亚萨克拉曼多的首都是什么”。但是该程序无法引用答案，只能引用逗号之前的第一部分。

我在做什么错了？

def quiz():
    score=0
    questionsRight=0
    fileName = input("Please enter the name of the quiz file: ")
    quizFile = open(fileName,"r")
    quizData = quizFile.readlines()
    questionno=1
    for x in range(10):
        for x in quizData:
            data = x.split(",")
        random.shuffle(quizData)
        questions = data[0]
        CorrectAnswer = data[1]

        print("Question #",questionno)
        print(questions)
        answer = input("What is your answer? ")
        if answer == CorrectAnswer:
            print("Correct!")
            score=score+1
            questionsRight=questionsRight+1
            questionno = questionno+1

        else:
            print("Incorrect.")
            questionno = questionno+1

    totalScore = (score / 10) * 100
    print("You got ",score," questions right, and a score of ",totalScore,"%.")

Answer 1

对此有一个stdlib库：Parameter(s) specified in the command line: -m lab51.mod -o lab51.txt --tmlim 300 Reading model section from lab51.mod... lab51.mod:58: syntax error in expression Context: ) + sum { m in MES } ( Std [ m ] - sum { i in MAYORISTA } * MathProg model processing error。

csv

import csv with open("path/to/your/quizfile.csv") as f: reader = csv.reader(f) quiz_qas = list(reader) # this could get *very* large -- take care if you have a large file. q, a = random.choice(quiz_qas) print(q) answer = input(">>> ") if answer == a: # user got the right answer else: # user failed甚至可以让您选择random.sample的随机k大小样本。

quiz_qas

Answer 2

随机播放列表并选择前n行
使用strip删除答案末尾的新行

更新的代码：

import random
def quiz():
    score=0
    questionsRight=0
    fileName = input("Please enter the name of the quiz file: ")
    quizFile = open(fileName,"r")
    quizData = quizFile.readlines()
    random.shuffle(quizData)
    questionno=1
    for i in range(5):
        x = quizData[i].strip()
        data = x.split(",")        
        question = data[0]
        CorrectAnswer = data[1]

        print("Question #",questionno)
        print(question)
        answer = input("What is your answer? ")
        if answer == CorrectAnswer:
            print("Correct!")
            score=score+1
            questionsRight=questionsRight+1
            questionno = questionno+1

        else:
            print("Incorrect.")
            print("Correc answer should be: "+CorrectAnswer)
            questionno = questionno+1
        print()

    totalScore = (score / 10) * 100
    print("You got ",score," questions right, and a score of ",totalScore,"%.")

改进：

使用csv模块。参见Adam Smith's answer。
