# 根据要求创建类，初始化，创建方法
class Employee:
    def __init__(self, name, salary):
        self.name = name
        self.salary = salary
    def printclass(self):
        try:
            print("{}'salary is {}, and his age is {}".format(self.name, self.salary, self.age))
        except:
            print("Error! No age")

# 根据要求输入：姓名，薪水，年龄            
name = input()
salary = int(input())
age = int(input())

# 先使用 name 和 salary 创建实例 e
e = Employee(name, salary)
e.printclass()

# 直接在实例 e 上添加属性：age
e.age = age
e.printclass()
