以下代码用于实现简单计算器实现,包括两个数基本的加减乘除运输:
# Filename :test.py # author by : www.shouce.ren # 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")
执行以上代码输出结果为:
选择运算: 1、相加 2、相减 3、相乘 4、相除 输入你的选择(1/2/3/4):2 输入第一个数字: 5 输入第二个数字: 2 5 - 2 = 3
