Question

如何为我的代码添加循环，使其重复10次，然后提供最终分数？这是我到目前为止尝试过的代码：

import random

randomNumber1 = random.randint ( 1,250 )
randomNumber2 = random.randint ( 1,250 )

def askQuestion():
    global randomNumber1
    global randomNumber2
    userAnswer = int( input( "What is " + str(randomNumber1) + " + " + \
                str(randomNumber2) + " ?: ") )
    return userAnswer

def checkAnswer (userAnswer):
    global randomNumber1
    global randomNumber2

    correctAnswer = randomNumber1 + randomNumber2
    print()
    if userAnswer == correctAnswer:
        print("Congratulations!")
    else:
        print( "It's wrong. The correct answer is", correctAnswer )

def main():
   userAnswer = askQuestion()
   checkAnswer(userAnswer)

main()

Answer 1

该脚本询问由ask_questions函数

的参数指定的10个问题

import random

def ask_questions(n):
    for q in range(n):
        n1 = random.randint(1, 250)
        n2 = random.randint(1, 250)

        user_answer = int(input('\nWhat is {} + {}? '.format(n1, n2)))
        if user_answer == n1 + n2:
            print("Congratulations!")
        else:
            print('It\'s wrong. The correct answer is {}'.format(n1 + n2))

def main():
    ask_questions(10)

main()

Answer 2

import operator, random

ops = {"+": lambda a, b: operator.add(a, b),
       "-": lambda a, b: operator.sub(a, b),
       "*": lambda a, b: operator.mul(a, b)}

def main():
    score = 0
    for q in range(10):
        a, b = random.randint(1, 10), random.randint(1, 10)
        op = random.choice(list(ops.keys()))
        ans = ops[op](a, b)

        print(a, op, b, "=", end = " ")
        user_input = int(input())

        if user_input == ans:
            score += 1

    print("Scored:", score)


main()

生成两个随机数以及运算符。程序循环10次然后输出最终得分。

<强>输出

7 - 6 = 1
9 + 4 = 13
9 + 8 = 17
1 - 1 = 0
9 + 7 = 16
5 + 7 = 12
7 * 8 = 56
8 - 8 = 0
4 + 3 = 7
9 + 6 = 15
Scored: 10

如何在我的代码中添加循环，使其重复10次，然后提供最终分数？
