Question

我正在创建一个程序，它将教我的小弟弟数学。但是例如，当程序说2 + 2时，我输入4就说“不正确！”。我做错了什么？

import random
import math

def addition():
    num1 = random.randint(1, 100)
    num2 = random.randint(1, 100)
    result = num1 + num2
    guess = input(str(num1) + " + " + str(num2) + " = ")#this is the line with problem
    if guess == result:
        print("Correct!")
    if guess != result:
        print("Incorrect!")
addition()

Answer 1

result是整数（例如，4），并且输入的猜测是字符串（例如，＆＃39; 4＆＃39;）。您需要将它们转换为相同的类型才能进行比较。 E.g：

result = str(num1 + num2)

Answer 2

将答案包裹到int

 guess = int(input(str(num1) + " + " + str(num2) + " = "))

Answer 3

将input转换为int：

import random
import math
def addition():
    num1 = random.randint(1, 5)
    num2 = random.randint(1, 5)
    result = num1 + num2
    guess = input(str(num1) + " + " + str(num2) + " = ")
    guess = int(guess) #input is string and it must be typecast to int
    if guess == result:
        print("Correct!")
    if guess != result:
        print("Incorrect!")
addition()
