Python 如何进行随机数学运算

所以我正在创建一个游戏，基本上它会问人们一些问题，关于他们想回答什么类型的问题，他们想回答多少，什么不想回答。我遇到了一个问题，如何处理随机的数学运算，比如加法、乘法和减法。这是我的全部代码，但我唯一需要帮助的部分是它在哪里显示“混合”，因为我需要弄清楚如何混合这三个操作

import random
correct = 0

while True:
    questions = int(input("Enter the amount of questions would you like to answer: "))
    difficulty = input("Enter the difficulty of questions you would like: Beginner,    Intermediate, or Advanced: ")
math = input("Would you like to do addition, subtraction, multiplication, or mixed: ")

if difficulty == "Beginner":
    for i in range(questions):
        if math == "multiplication":
            beg1 = random.randint(1, 10)
            beg2 = random.randint(1, 10)
            prod = beg1 * beg2

            begAns = input("What is " + str(beg1) + " times " + str(beg2) + "? ")

            if int(begAns) == prod:
                print("That's right -- well done.\n")
                correct += 1
            else:

要随机选择+、-或*中的一个，并将其应用于两个数字：

import random
from operator import add, sub, mul

ops = (add, sub, mul)
op = random.choice(ops)

beg1, beg2 = random.randint(1,10), random.randint(1,10)

ans = op(beg1, beg2)

为了将来的参考，您应该更努力地将代码缩减到需要帮助的特定部分。我没有投反对票，但这可能是其他人投反对票的原因。你的代码也可以从使用几个函数中获益，你在一个地方做了太多的事情。
