Question

我一直试图进行一个数学测验，询问一个随机问题，然后再问一个10次的随机问题，我的问题是它会一次又一次地问一个随机的问题同样的问题等

import random

opList = ["+", "*", "-"]
numberofQuestions = 10
num1 = random.randint(0, 10)
num2 = random.randint(0, 10)
ops = random.choice(opList)
question = "%d %s %d" % (num1, ops, num2)
answer = eval(question)
totalScore = 0


childName = input("Enter your name: ")
print("Thank you for signing up for Arithmetic Quiz " + childName)
for i in range(numberofQuestions):
    reply = int(input("What is " + question + " ? "))
    if reply == answer:
        print("Correct!!")
        totalScore += 1
    else:
        print("Incorrect!!")

Answer 1

列出以下几行：

num1 = random.randint(0, 10)
num2 = random.randint(0, 10)
ops = random.choice(opList)
question = "%d %s %d" % (num1, ops, num2)
answer = eval(question)

你有意味着他们只评估一次，为每个变量分配随机选择但静态的值。

您需要在for循环中移动这些语句，以便每次需要新值时重新评估它们

Answer 2

问题是你只生成一次问题（和问题的组成部分）。我的建议是生成一个像这样的新函数：

...

def question_answer():
    num1 = random.randint(0, 10)
    num2 = random.randint(0, 10)
    ops = random.choice(opList)
    question = "%d %s %d" % (num1, ops, num2)
    answer = eval(question)
    return question, answer

for i in range(numberofQuestions):
    question, answer = question_answer()
    ...

Answer 3

您没有更新num1，num2，ops，问题和答案变量。您需要将它们移动到for循环中。否则它们将始终等于它们被分配的第一个值。
