类属性查找与绑定方法

class luffystudent:
    def __init__(self,name,sex,age):
        self.name=name
        self.sex=sex
        self.age=age


    school='luffycity'
    def learn(self,x):
        print('%s is learning %s' %(self.name,x))
    def eat(self):
        print('is eating')
    def sleep(self):
        print('is sleeping')


#后产生对象
stu1=luffystudent('sunny','nan','28')
stu2=luffystudent('alex','男','30')
stu3=luffystudent('egon','nan','31')
# print(stu1.__dict__)
# print(stu2.__dict__)
# print(stu3)

#对象：技能与特征的结合体
#类：是一系列对象相似的特征与技能结合体
#类中的数据属性：是所有对象共有的
# print(luffystudent.school,id(luffystudent.school))
# print(stu1.school,id(stu1.school))
# print(stu2.school,id(stu2.school))
#类中的函数属性:是绑定到对象的使用的，绑定到不同对象，方法不同，对象调用绑定方法时
#会把本身当做第一个对象传入，传给self
# print(luffystudent.learn)
#luffystudent.learn(stu1)

# print(stu1.learn)
stu1.learn(1)
# print(stu2.learn)
stu2.learn(2)
# print(stu3.learn)
