python面向对象训练

代码如下：

class Test:
    def __getattr__(self, item):
        print("getattr方法被调用")
        return item
    def __init__(self,name,age):
        self.name = name
        self.age = age
        print("init方法被调用")
    def __repr__(self):
        return "repr方法被调用"
    def __del__(self):
        print("实例被销毁")
t=Test("Tom",12)
print("name属性值为%s"%t.name)
t.sex
print(t)
