Python测验程序-阅读CSV并解析问题/答案
Python测验程序-阅读CSV并解析问题/答案
提问于 2018-12-01 11:39:37
我在Python中有一个简单的测验，但有问题。它以“问题，答案”格式读取逗号分隔的文本文件。该程序可以很好地阅读测验并输出问题，但我无法获得要随机化的问题和"CorrectAnswer“变量来读取正确答案。
例如，如果问题是“加利福尼亚州的首府是什么？”答案是“萨克拉门托”，CSV文件是这样写的：“加州的首府是萨克拉门托”。但是程序不能引用答案，只能引用逗号前的第一部分。
我做错了什么？
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,"%.")回答 2

有一个用于此的stdlib库：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 failedrandom.sample甚至可以让你随机选择k大小的quiz_qas样本。
quiz = itertools.sample(quiz_qas, num_questions)
for q, a in quiz:

- 整理列表并选择first
nlines -
strip
结尾处的新行
更新代码：
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,"%.")
quiz()输出：
