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。
import random
print ('Welcome to my quiz. Enter the correct answer for the given math equation.')
print ('Enter -1 to quit')
Score = 0
UserInput = 0

CorrectAnswer3 = 0
IncorrectAnswer = 0
num1 = 0
num2 = 0
num3 = 0
num4 = 0
num5 = 0
num6 = 0
ans = 0
while ans != -1:
print ('\n')
num1 = random.randint (1,12)
num2 = random.randint (1,12)
num3 = random.randint (1,25)
num4 = random.randint (1,25)
num5 = random.randint (50,100)
num6 = random.randint (1,25)
CorrectAnswer = num1 * num2
CorrectAnswer2 = num3 + num4
CorrectAnswer3 = num5 - num6
print ('What is ', num1, ' x ', num2, '?')
ans = int (input ('Answer: '))
if ans == CorrectAnswer:
print ('Correct! ')
Score = Score + 1
else:
print ('Incorrect')
print ('The correct answer is: ', CorrectAnswer)
Score = Score -1
print ('What is ', num3, ' + ', num4, '?' )
ans = int (input ('Answer: '))
if ans == CorrectAnswer2:
print ('Correct! ')
Score = Score + 1
else:
print ('Incorrect')
print ('The correct answer is: ', CorrectAnswer2)
Score = Score -1
print ('What is ', num5, ' - ', num6, '?' )

尝试以下代码：
import random
print ('Welcome to my quiz. Enter the correct answer for the given math equation.')
print ('Enter -1 to quit')
Score = 0
UserInput = 0
CorrectAnswer = 0
CorrectAnswer2 = 0
CorrectAnswer3 = 0
IncorrectAnswer = 0
num1 = 0
num2 = 0
num3 = 0
num4 = 0
num5 = 0
num6 = 0
ans = 0
print('\n')
num1 = random.randint (1,12)
num2 = random.randint (1,12)
num3 = random.randint (1,25)
num4 = random.randint (1,25)
num5 = random.randint (50,100)
num6 = random.randint (1,25)
CorrectAnswer = num1 * num2
CorrectAnswer2 = num3 + num4
CorrectAnswer3 = num5 - num6
print ('What is ', num1, ' x ', num2, '?')
ans = int (input ('Answer: '))
if ans != -1:
if ans == CorrectAnswer:
print ('Correct! ')
Score = Score + 1
else:
print ('Incorrect')
print ('The correct answer is: ', CorrectAnswer)
Score = Score -1
print ('What is ', num3, ' + ', num4, '?' )
ans = int (input ('Answer: '))
if ans == CorrectAnswer2:
print ('Correct! ')
Score = Score + 1
else:
print ('Incorrect')
print ('The correct answer is: ', CorrectAnswer2)
Score = Score -1
print ('What is ', num5, ' - ', num6, '?' )
ans = int (input ('Answer: '))
if ans == CorrectAnswer3:
print ('Correct! ')
Score = Score + 1
else:
print ('Incorrect')
print ('The correct answer is: ', CorrectAnswer3)
Score = Score - 1
else:
pass
print('\n')

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。

最简单的方法。
我刚刚在每个input后面添加了if ans == 1: break。
import random
print ('Welcome to my quiz. Enter the correct answer for the given math equation.')
print ('Enter -1 to quit')
Score = 0
while True:
print ('\n')
num1 = random.randint (1,12)
num2 = random.randint (1,12)
num3 = random.randint (1,25)
num4 = random.randint (1,25)
num5 = random.randint (50,100)
num6 = random.randint (1,25)
CorrectAnswer = num1 * num2
CorrectAnswer2 = num3 + num4
CorrectAnswer3 = num5 - num6
print ('What is ', num1, ' x ', num2, '?')
ans = int (input ('Answer: '))
if ans == -1:
break
if ans == CorrectAnswer:
print ('Correct! ')
Score = Score + 1
else:
print ('Incorrect')
print ('The correct answer is: ', CorrectAnswer)
Score = Score -1
print ('What is ', num3, ' + ', num4, '?' )
ans = int (input ('Answer: '))
if ans == -1:
break
if ans == CorrectAnswer2:
print ('Correct! ')
Score = Score + 1
else:
print ('Incorrect')
print ('The correct answer is: ', CorrectAnswer2)
Score = Score -1
print ('What is ', num5, ' - ', num6, '?' )
ans = int (input ('Answer: '))
if ans == -1:
break
if ans == CorrectAnswer3:
print ('Correct! ')
Score = Score + 1
else:
print ('Incorrect')
print ('The correct answer is: ', CorrectAnswer3)
Score = Score - 1
print ('\n')
print ('Well done, Your final score is: ', Score)顺便说一句。一些小贴士。
如果您稍后进行初始化(通过分配新值)，则不需要在顶部初始化变量。
Python变量通常从小写开始(类从大写开始)。
你可以用更短的方式增加和减少x += 1
如果参数用空格分隔是很好的，例如。random.randint(1, 12)
函数后的空格(如Python3中的input或print )不是必需的。
您可以连接新的行和字符串，例如。print('\nWell done, Your final score is:', Score) BTW.默认情况下，print中的参数以空格分隔。
对于Python 3.6+，您可以使用format-string，它更简单(请参阅'之前的f )：
print(f'\nWell done, Your final score is: {Score}')或
print(f'What is {num3} + {num4}?')
