我在做什么错，我不确定如何修复我的代码

Question

我正在尝试在python中进行数学测验，而当我输入正确的答案后，大多数代码都可以正常工作时，代码始终无法正确打印。

import random


Name=input("What is your name?")
Class=input("wWhat class are you in?")
print("Welcome" ,Name, "to the Maths Quiz!!")

QuestionNumber=0
Operations=["+","-","x"]

Num1=random.randint(1,30)
Num2=random.randint(1,30)     
answer=0

while QuestionNumber < 10:
    QuestionNumber=QuestionNumber+1
    print("What is", Num1 ,random.choice(Operations),Num2)
    guess=int(input("What is the answer to this question?"))

    if Operations=="+":
        answer=Num1+Num2

    elif Operations=="-":
            answer=Num1-Num2

    elif Operations=="x":
        answer=Num1*Num2

    if guess==answer:
        print ("Correct")

    else:
        print("Incorrect")

Answer 1

if Operations=="+":

您正在将List对象与字符串进行比较。 好像错了 正如乔恩（Jon）所述，这导致answer始终保持为0。

你应该换成这样

while QuestionNumber < 10:
    QuestionNumber=QuestionNumber+1
    operation = random.choice(Operations)
    print("What is", Num1 ,operation, Num2)
    guess=int(input("What is the answer to this question?"))

    if operation =="+":
        answer=Num1+Num2

    elif operation =="-":
            answer=Num1-Num2

    elif operation =="x":
        answer=Num1*Num2

    if guess==answer:
        print ("Correct")

    else:
        print("Incorrect")

跟踪当前操作是什么，并使用该值进行比较
