如何使用Python编程生成并输出适当的数学口算题目，例如加减乘除运算？

在Python中生成随机数学口算题目，我们可以利用`random`模块和字符串格式化功能。下面是一个简单的例子，它会生成加法、减法、乘法和除法的随机题目：

import random

def generate_arithmetic_problem():
    operators = ['+', '-', '*', '/']
    a = random.randint(1, 100)  # 随机整数范围
    b = random.randint(1, 100)

    operation = random.choice(operators)
    
    if operation == '+':
        result = a + b
        problem = f"{a} {operation} {b} = ?"
    elif operation == '-':
        while b >= a:  # 确保减数小于被减数
            b = random.randint(1, 99)
        result = a - b
        problem = f"{a} {operation} {b} = ?"
    elif operation == '*':
        result = a * b
        problem = f"{a} {operation} {b} = ?"
    else:  # operation == '/'
        while b == 0 or (a % b != 0 and b <= a):  # 确保除数不为零且非整除
            b = random.randint(1, 99)
        result = int(a / b)
        problem = f"{a} {operation} {b} = ?"

    return problem, result

# 测试函数
problem, answer = generate_arithmetic_problem()
print(f"题目：{problem}")
print(f"答案：{answer}")

# 若要生成更多的题目，可以循环调用generate_arithmetic_problem()函数

运行这段代码，你可以得到一系列随机的数学口算题目，比如 "45 + 63 = ?" 或者 "87 * 2 = ?"。
