1.继承是python面向对象的三大特性之一，是一种创建新类的方式，python中的继承，可以继承一个或者继承多个父类，新建的类被称之为派生类或者子类，被继承的类是父类，可以称之为基类，超类，继承是实现代码重用的重要方式。
#coding=utf-8;
class father(object):
#父类初始化方法
def __init__(self,id):
self.id=id;
#父类类方法
@classmethod
def classmethod_father(cls,id,where):
print(id,"father working...",where);
#父类静态方法
@staticmethod
def staticmethod_father(a,b,c):
print(a,b,c,"father static method...");
#父类普通方法
def publicmethod_father(self,id,name):
#id=self.id;
#name=self.name;
print("id:",id,"name:",name);
class son(father):
def __init__(self,sonid):
super().__init__(id);
self.sonid=sonid;
@classmethod
def classmethod_son(cls,sonid,sondo):
print("调用者：",sonid,"son classmethod_son")
@staticmethod
def staticmethod_son(who):
print("调用者:",who,"son static method ...");
def public_son(self,who):
print("调用者:",who,"son public method...");
class grandson(son):
def __init__(self,grandson_id):
self.grandson_id=grandson_id;
@classmethod
def classmethod_grandson(cls,who):
print("调用者",who,"grandson classmethod ...");
@staticmethod
def staticgrandson(who):
print("调用者","grandson staticmethod...");
def public_grandson(self,who):
print("调用者",who,"grandson public...");
#设置一个变量
fathername="tom";
fatherid=123;
#father实例化
f=father(fatherid);
f.classmethod_father(fatherid,"北京");
f.staticmethod_father(111,222,333);
f.publicmethod_father(fatherid,fathername);
#father类调用
father.classmethod_father(888,"father类调用");
father.staticmethod_father("aaa","bbb","ccc");
father.publicmethod_father(1,100,"tom")
#son实例调用
s = son(12345);
s.classmethod_father(fatherid,"北京");
s.staticmethod_father(111,222,333);
s.publicmethod_father(fatherid,fathername);
s.classmethod_son(12345,"上海");
s.staticmethod_son("son")
s.public_son("son");
#grandson实例调用
gs=grandson("1234578");
gs.classmethod_grandson("grandson");
gs.staticgrandson("grandson");
gs.public_grandson("grandson");
运行结果：
123 father working... 北京 111 222 333 father static method... id: 123 name: tom 888 father working... father类调用 aaa bbb ccc father static method... id: 100 name: tom 123 father working... 北京 111 222 333 father static method... id: 123 name: tom 调用者： 12345 son classmethod_son 调用者: son son static method ... 调用者: son son public method... 调用者 grandson grandson classmethod ... 调用者 grandson staticmethod... 调用者 grandson grandson public...
