python 析构函数：__del__()

'''析构函数：__del__()    释放对象是自动调用'''class Person(object):    def run(self):        print("run")    def eat(self, food):        print("eat " + food)    def __init__(self, name, age, height, weight):        self.name = name        self.age = age        self.height = height        self.weight = weight    def __del__(self):        print("这里是析构函数")per = Person("hanmeimei", 20, 170, 55)#释放对象del per#对象释放以后就不能再访问了#print(per.age)#在函数里定义的对象，会在函数结束时自动释放，这样可以用来减少内存空间的浪费def func():    per2 = Person("aa", 1, 1, 1)func()while 1:    pass
