Python计算器代码实现详解

示例代码实现

以下是一个用Python实现的简单计算器功能代码，可以执行加、减、乘、除运算：

def calculator(): print("简单计算器") print("选择操作：") print("1. 加法") print("2. 减法") print("3. 乘法") print("4. 除法") choice = input("输入选择(1/2/3/4): ") num1 = float(input("输入第一个数字: ")) num2 = float(input("输入第二个数字: ")) if choice == '1': print(f"结果: {num1} + {num2} = {num1 + num2}") elif choice == '2': print(f"结果: {num1} - {num2} = {num1 - num2}") elif choice == '3': print(f"结果: {num1} * {num2} = {num1 * num2}") elif choice == '4': if num2 != 0: print(f"结果: {num1} / {num2} = {num1 / num2}") else: print("错误：除数不能为零") else: print("无效输入") calculator()

代码说明

• 该代码定义了一个calculator函数，提供基本的四则运算功能
• 用户可以通过输入数字选择运算类型
• 程序会提示用户输入两个操作数
• 根据用户选择执行相应运算并输出结果
• 除法运算包含了对除数为零的检查

扩展建议

如需扩展功能，可以考虑：

• 添加更多数学运算如幂运算、模运算
• 增加历史记录功能
• 实现图形用户界面版本
• 添加科学计算功能

该代码可以在任何Python环境中运行，只需复制粘贴即可使用。
