修改属性2
https://www.nowcoder.com/practice/7831806be5684ad6ac0f8b43e3e3558e
class employee:
def __init__(self, name, salary):
self.name = name
self.salary = salary
def printclass(self):
print(f"{self.name}'salary is {self.salary}, and his age is {self.age}")
name = input()
salary = input()
age = input()
e = employee(name, salary)
print(hasattr(e, age))
if hasattr(e, 'age'):
e.printclass()
else:
setattr(e, "age", age)
e.printclass()
setattr() 函数对属性进行赋值：
setattr(object, name, value)
如果属性是已经存在的用单引号，如果是未存在的，需要先创建再赋值，这时需要用双引号
hasattr(object, name)判断一个对象里面是否有name属性或者name方法,返回BOOL值,有name特性返回True, 否则返回False。
