如何在python测验中退出
如何在python测验中退出
提问于 2019-11-18 19:48:30
这是一个基本的数学测验，我必须做，但我还没有弄清楚如何让游戏退出。
我只是一个初学python的学生，所以请给我任何建议，并解释我做错了什么。如果你有任何改进的想法，那么如果可能的话，我请求你分享它。

我已经使用列表减少了变量的数量。我还为字符串添加了f标志，这样就不会滥用连接。总的来说，我稍微改进了你的代码(在视觉上) :)
import random
import sys
import time
print ('Welcome to my quiz. Enter the correct answer for the given math equation.')
print ('Enter -1 to quit \n')
Score = 0
ans = None
num = [random.randint(1,12) for i in range(6)]
num[4] = random.randint(50,100)
CorrectAnswers = [
num[0] * num[1],
num[2] + num[3],
num[4] - num[5]]
while True:
print (f'What is {num[0]} x {num[1]}?')
ans = int(input('Answer: '))
if ans == CorrectAnswers[0]:
print ('Correct!')
Score += 1
elif ans == -1:
break
else:
print (f'Incorrect \n The correct answer is: {CorrectAnswers[0]}')
Score -= 1
print (f'What is {num[2]} + {num[3]}?' )
ans = int (input('Answer: '))
if ans == CorrectAnswers[1]:
print ('Correct!')
Score += 1
elif ans == -1:
break
else:
print (f'Incorrect \n The correct answer is: {CorrectAnswers[1]}')
Score -= 1
print (f'What is {num[4]} - {num[5]}?' )
ans = int(input('Answer: '))
if ans == CorrectAnswers[2]:
print ('Correct!')
Score += 1
elif ans == -1:
break
else:
print (f'Incorrect \n The correct answer is: {CorrectAnswers[2]}')
Score -= 1
print (f'\n Well done, Your final score is: {Score}')
time.sleep(2)
sys.exit()关于这项任务。在Python中退出的方法有很多种，但我仍然选择了sys.exit()。如果您想使这段代码完美，请阅读Python中的OOP并查看PEP8，这是Python语言的代码风格。
