编程口算题输答案后判断对错，Python编程语句怎么写？

Posted 2023-03-11

import random

flag = ["+","-","×","÷"]

a1 = random.randint(0,9)

a2 = random.randint(0,9)

i_flag = random.randint(0,3)

str = f"a1 flag[i_flag] a2 = "

result = None

if flag[i_flag] == "+":

   result = a1 + a2

elif flag[i_flag] == "-":

     result = a1 - a2

elif flag[i_flag] == "×":

    result = a1 * a2

elif flag[i_flag] == "÷":

    result = a1 / a2

else:

    pass

ins = input(str)

if f"result" == ins:

   print(f"ins is correct! ")

else:

   print(f"ins is wrong, right answer is : strresult")

参考技术A

import random

flag = ["+","-","×","÷"]

a1 = random.randint(0,9)

a2 = random.randint(0,9)

i_flag = random.randint(0,3)

str = f"a1 flag[i_flag] a2 = "

result = None

if flag[i_flag] == "+":

   result = a1 + a2

elif flag[i_flag] == "-":

     result = a1 - a2

elif flag[i_flag] == "×":

    result = a1 * a2

elif flag[i_flag] == "÷":

    result = a1 / a2

else:

    pass

ins = input(str)

if f"result" == ins:

   print(f"ins is correct! ")

else:

   print(f"ins is wrong, right answer is : strresult")
