编写个程序，求出两个整数的和，差，积，商（完整的）还有整商，余数

编写一个简单的Python程序，可以计算两个整数的和、差、积、商以及整除后的商和余数：

def calculate(a, b):
    # 计算和、差
    sum_result = a + b
    difference = a - b
    
    # 计算积、商
    product = a * b
    quotient = a / b
    
    # 商和余数（处理浮点数除法）
    try:
        int_quotient = a // b
        remainder = a % b
    except ZeroDivisionError:
        int_quotient = None
        remainder = None
        print("注意：除数不能为0")

    return {
        "和": sum_result,
        "差": difference,
        "积": product,
        "商": float(quotient),  # 返回浮点数表示精确的小数商
        "整商": int_quotient,   # 整除商，如果除数为0则为None
        "余数": remainder,
    }

# 示例输入
num1 = 15
num2 = 4

result = calculate(num1, num2)
print(f"对于数字 {num1} 和 {num2}:")
for key, value in result.items():
    print(f"{key}: {value}")
