开发一个给小学生练习100以内数加、减 (大数减小数)、乘、除 (能整除) 运算的程序

以下是一个简单的Python程序，可以帮助小学生练习100以内数加、减、乘、除运算：

import random

def addition():
    num1 = random.randint(1, 100)
    num2 = random.randint(1, 100 - num1)
    result = num1 + num2
    print(f"What is {num1} + {num2}?")
    return result

def subtraction():
    num1 = random.randint(1, 100)
    num2 = random.randint(1, num1)
    result = num1 - num2
    print(f"What is {num1} - {num2}?")
    return result

def multiplication():
    num1 = random.randint(1, 10)
    num2 = random.randint(1, 10)
    result = num1 * num2
    print(f"What is {num1} x {num2}?")
    return result

def division():
    num1 = random.randint(1, 100)
    factors = [i for i in range(1, num1 + 1) if num1 % i == 0]
    num2 = random.choice(factors)
    result = num1 // num2
    print(f"What is {num1} ÷ {num2}?")
    return result

score = 0

for i in range(10):
    question_type = random.choice(["addition", "subtraction", "multiplication", "division"])
    if question_type == "addition":
        answer = addition()
    elif question_type == "subtraction":
        answer = subtraction()
    elif question_type == "multiplication":
        answer = multiplication()
    else:
        answer = division()
    user_answer = int(input("Enter your answer: "))
    if user_answer == answer:
        print("Correct!")
        score += 1
    else:
        print("Incorrect!")
    
print(f"You scored {score} out of 10.")

这个程序会随机生成10道加、减、乘、除运算题目，每道题目的数字都在1到100之间。用户需要输入答案，程序会根据用户的回答给出正确或错误的反馈，并在最后输出分数。注意，除法运算的答案使用了整数除法（`//`），这样就能保证答案是整数。
