编写一个100以内的整数加减乘除练习器

好的，我可以为您提供一个简单的Python程序，可以让您练习100以内的整数加减乘除。

import random

def generate_question():
    """生成随机的加减乘除算式"""
    num1 = random.randint(1, 100)
    num2 = random.randint(1, 100)
    operator = random.choice(['+', '-', '*', '/'])
    if operator == '+':
        answer = num1 + num2
    elif operator == '-':
        answer = num1 - num2
    elif operator == '*':
        answer = num1 * num2
    else:
        # 除法操作时需要保证能够整除
        answer = num1 // num2
        num1 = answer * num2
    question = f"{num1} {operator} {num2} = "
    return question, answer

def main():
    """主函数，用于运行练习器"""
    print("欢迎使用100以内的整数加减乘除练习器！")
    print("请输入您要练习的题目数量：")
    num_questions = int(input())
    correct_answers = 0
    for i in range(num_questions):
        question, answer = generate_question()
        print(f"第{i+1}题：{question}")
        user_answer = int(input())
        if user_answer == answer:
            print("回答正确！")
            correct_answers += 1
        else:
            print(f"回答错误，正确答案为{answer}")
    print(f"您一共回答了{num_questions}道题，其中{correct_answers}道题回答正确。")

if __name__ == '__main__':
    main()

这个程序会生成随机的加减乘除算式，让您输入答案，然后判断您的答案是否正确。您可以输入练习题目的数量，程序会自动生成相应数量的练习题目。祝您练习愉快！
