Python 将随机运算符add、mul或sub转换为字符串+；*-

很抱歉，我是python的新手，在其他问题上找不到答案

我要做的是将随机数学运算符转换为字符串，以便在打印语句问题中使用它。这就是我所做的，我知道这是错误的，但我想让你看看我的逻辑

任何帮助都将不胜感激

while not exitProgram:
    for count in range(10):
        print ("Question ", (count+1),":")
        integer1 = random.randint(0,10)
        print (integer1) #This is used for testing
        integer2 = random.randint(0,10)
        print (integer2)#Again used for testing
        ops = add,sub,mul
        op = random.choice(ops)
        print (op) #testing
        correctAnswer = op(integer1, integer2)
        print (correctAnswer)
        opPrint = ""
        if op == <built-in function sub>:
            opPrint = "-"
            print (opPrint)
        if op == "<built-in function mul>":
            opPrint = "*"
            print (opPrint)
        if op == "<built-in function add>":
            opPrint = "+"
            print (opPrint)

        print ("What is " ,integer1, opPrint, integer2)
        answer = int(input("Please enter your answer\n"))

不退出程序时：
对于范围（10）内的计数：
打印（“问题”，（计数+1），“：”）
整数1=random.randint（0,10）
打印（整数1）#用于测试
整数2=random.randint（0,10）
打印（整数2）#再次用于测试
ops=添加、分段、分段
op=随机选择（ops）
打印（op）#测试
correctAnswer=op（整数1，整数2）
打印（正确答案）
opPrint=“”
如果op==：
opPrint=“-”
打印（opPrint）
如果op==“”：
opPrint=“*”
打印（opPrint）
如果op==“”：
opPrint=“+”
打印（opPrint）
打印（“What is”，integer1，opPrint，integer2）
answer=int（输入（“请输入您的答案”））

您应该查看该模块，该模块将标准操作员作为一组功能提供访问权限。这里需要

运算符、
运算符、
子运算符和
运算符

与其使用
if
/
elif
/
else
链，不如使用字典在代码引用和字符串之间进行映射

我会这样写你的程序

import random
from operator import __add__, __sub__, __mul__

ops = __add__, __sub__, __mul__

symbols = {
    __add__: '+',
    __sub__: '-',
    __mul__: '*',
}

score = 0

for count in range(10):

    p1 = random.randint(0, 10)
    p2 = random.randint(0, 10)
    op = random.choice(ops)

    sum_text = '%d %s %d' % (p1, symbols[op], p2)

    print('\nQuestion %d: what is %s?' % (count + 1, sum_text))
    answer = int(input('Please enter your answer: '))

    correct_answer = op(p1, p2)

    if answer == correct_answer:
        print('Correct!')
        score += 1
    else:
        print("Sorry, that's wrong")
        print('The correct answer is %d' % correct_answer)

print('You scored a total of %d out of %d' % (score, 10))

你的代码没有任何意义；将一个对象与类似字符串的字符串进行比较是行不通的（除了看看它是否真的是那个字符串）。考虑把你的运算符函数放在字典<代码> {'+':Addio.}中，这将使你的生活变得简单多了。我读到“把一个对象比作一个字符串就好像永远不会去工作”，并在试图寻找原因。博罗丁错过了“那个”，对不起！谢谢你所有的帮助help@RH84这回答了你的问题吗？
