pathon for循环两个随机数相加

import random for i in range(1,20):   a=random.randint(1,20) n=i+a b=int(input(“{}+{}=”.format(i,a)) if n1=n  Print(“恭喜你回答正确”) else    Print(“计算错误，加油啊！”) print(“正确答案为{}.format(n)”)  

import random   #引入随机数的模块 

# 产生两个随机整数（0-9）
number1 = random.randint(0, 9)
number2 = random.randint(0, 9)

# 输入答案
answer = eval(input("What is " + str(number1) + " + " 
    + str(number2) + "? "))

# 显示结果  
print(number1, "+", number2, "=", answer, 
    "is", number1 + number2 == answer)
