我试图制作一个可以在测验中随时输入“ q”时退出游戏的函数，但是它不起作用，它在intcheck函数下并且是strchecker，我还有另一个strchecker功能也许就是为什么它不起作用。我知道它需要打破一个循环，我只是python的初学者。
score = 0
def strchecker(question):
valid=False
while not valid:
user_Name = input(question)
if user_Name!="":
valid=True
return user_Name
else:
print("Please do not leave username blank")
print("*********************Welcome to the Te Reo Maori Quiz************************\n"
"You will be give a series of 6 questions,\nto answer you will enter an answer between 1 and 4.\n\nBest of Luck,and remember if you would like to quit the game just press enter :)\n")
user_Name = strchecker("Please enter your username:\n")
print("Hi", user_Name,"Here is your first question:\n")
keep_going=""
while keep_going=="":

答案 0 :(得分：1)
一个问题是您正在检查错误函数的出口，答案被提供给int检查器，而strchecker仅给出错误。我已经移动了一些代码，并对其进行了一些简化-仍然可以对代码进行一些清理-不需要那么多的for循环。另外，问题/答案数组有点“笨拙”-在这里，我将它们全部放入一个二维数组（列表）中。
此外，我正在使用sys.exit()退出-而不是终止外部循环：
import sys
def checkname(name):
valid = False
while not valid:
user_Name = input(name)
if user_Name != "":
valid = True
return user_Name
else:
print("Please do not leave username blank")
def checkans(question, low, high):
valid = False
while not valid:
error = "Whoops! Please enter an integer between {} and {}\n".format(low, high)
response = input("Please enter your answer or press 'q' to quit:\n")
try:
answer = int(response)
if low <= answer <= high:
return answer
else:
print(error)
print()
except ValueError:
if (response == 'q'):
print("Quitting Game")
sys.exit()
else:
print(error)
