Python 如何打印add、mul、sub函数？

我正在这样做：

        opers = (add, sub, mul)
        rand_choice = random.choice(opers)
        num1 = random.randint(1, operand_level)
        num2 = random.randint(1, operand_level)
        prod = rand_choice(num1, num2)

我想打印问题是sub、add还是mul 所以

您可以通过

\uuuu name\uuuu

属性执行此操作，因此：

print('what is {}({}, {})'.format(rand_choice.__name__, num1, num2))

它有助于发布一个无需修改即可运行的示例。要使示例正常工作，需要以下几行代码：

from operator import add,sub,mul
import random
operand_level = 10

要打印运算符，请将符号添加到选项列表中：

opers = ('+',add),('-',sub),('x',mul)
symbol,function = random.choice(opers)
num1 = random.randint(1, operand_level)
num2 = random.randint(1, operand_level)
result = function(num1, num2)
print("what is {}{}{}? [{}]".format(num1,symbol,num2,result))

多次运行的输出：

what is 1x9? [9]
what is 7-5? [2]
what is 9-4? [5]
what is 10+4? [14]

你想做什么？你为什么要取代rand_choice？不知道我是否明白你想要什么。。。请尝试打印（“what is”，num1）谢谢！下一次我肯定会粘贴我所有的代码，这样它就可以运行而无需修改

what is 1x9? [9]
what is 7-5? [2]
what is 9-4? [5]
what is 10+4? [14]
