Question

我是Python的初学者，我正在创建一个简短的测验。

我创建了一个简短视频，以准确显示正在发生的事情： https://www.youtube.com/watch?v=aHRAr0T-i-Q&feature=youtu.be

我怎么能拥有它，所以它提出了一个问题，“Conor Mcgregor是谁？”然后打印答案，如何阻止它在答案下面再次重复问题？

我的代码：

while True:
    question = input("Who is Conor Mcgregor?")
    print("A) A Chef")
    print("B) A Fighter")
    print("C) A Doctor")
    if len(question):
        answer = question
        if answer == "B" or answer == "b":
            print("Well Done! Conor Mcgregor is an MMA Fighter.")
            break
        elif answer == "A" or answer == "C":
            print("Wrong Answer!")
            break
        else:
            print("Error")

运行时，其行为如下：

C:\Users\msi\AppData\Local\Programs\Python\Python36-32\python.exe C:/Users/msi/PycharmProjects/Reboot/Quiz.py
Who is Conor Mcgregor?
A) A Chef
B) A Fighter
C) A Doctor
Who is Conor Mcgregor?

我怎样才能让它提出问题，然后跟进答案？我必须先按一个按钮才能继续回答，然后当答案显示时，问题就出现了。

提前谢谢你！

Answer 1

您需要打印问题然后要求输入：

print("Who is Conor Mcgregor?")
print("A) A Chef")
print("B) A Fighter")
print("C) A Doctor")
answer = input('A/B/C?: ')

Answer 2

你可以用循环

来做

while True:
    print("Who is Conor Mcgregor? ")
    print("A) A Chef")
    print("B) A Fighter")

    answer = raw_input()
    if answer == "B":
        print("Correct!")
        break
    elif answer == "A":
        print("Wrong! The correct answer was B! Conor Mcgregor is a Fighter.")
        break
    print("Please enter a valid answer!")

或使用功能

def question():
    print("Who is Conor Mcgregor? ")
    print("A) A Chef")
    print("B) A Fighter")

    answer = raw_input()
    if answer == "B":
        print "Correct!"
        return True
    elif answer == "A":
        print "Wrong! The correct answer was B! Conor Mcgregor is a Fighter."
        return True
    print("Please enter a valid answer!")
    question()
question()

如果使用python 2.7

，还需要更改raw_input的输入
