## Python计算器：用于实现简单计算器实现，包括两个数基本的加减乘除运算 ##

代码如下：

>     # 定义函数
>     def add(x, y):
>         """相加"""
>         return x + y
>     
>     def subtract(x, y):
>         """相减"""
>         return x - y
>     
>     def multiply(x, y):
>         """相乘"""
>         return x * y
>     
>     def divide(x, y):
>         """相除"""
>         return x / y
>     
>     # 用户输入
>     print("选择运算：")
>     print("1、相加")
>     print("2、相减")
>     print("3、相乘")
>     print("4、相除")
>     
>     choice = input("输入你的选择(1/2/3/4):")
>     
>     num1 = int(input("输入第一个数字: "))
>     num2 = int(input("输入第二个数字: "))
>     
>     if choice == '1':
>         print(num1, "+", num2, "=", add(num1, num2))
>     
>     elif choice == '2':
>         print(num1, "-", num2, "=", subtract(num1, num2))
>     
>     elif choice == '3':
>         print(num1, "*", num2, "=", multiply(num1, num2))
>     
>     elif choice == '4':
>         print(num1, "/", num2, "=", divide(num1, num2))
>     else:
>         print("非法输入")
