Python面向对象基础详解编程语言

print("Person.__doc__:" , Person.__doc__)#类的文档字符串 print("Person._name_:", Person.__name__)#类名 print("Person.__module__:",Person.__module__)#类定义所在的模块（类的全名是__main__.className，如果类位于一个导入模块mymod中，那么className.__module__ 等于 mymod） print("Person.__bases__", Person.__bases__)#类的所有父类构成元素（包含了一个由所有父类组成的元组） print("Person.__dict__:", Person.__dict__)# 类的属性（包含一个字典，由类的数据属性组成） emp1=Person("Zara","female",18) emp2=Person("Mi","male",18) emp1.displayEmployee()

Person.__doc__: 人的基类 

Person._name_: Person 

Person.__module__: __main__ 

Person.__bases__ ( class object ,) 

Person.__dict__: {__module__: __main__, __doc__: 人的基类, perCount: 0, __init__: function Person.__init__ at 0x108bcce18 , displayCount: function Person.displayCount at 0x108bccd08 , displayEmployee: function Person.displayEmployee at 0x108bccea0 , __dict__: attribute __dict__ of Person objects , __weakref__: attribute __weakref__ of Person objects }

self表示类的实例，非类本身。

2. inherit

class Person: 

 人的基类 

 def __init__(self, name, gender, age): 

 self.name=name 

 self.gender=gender 

 self.age=age 

 def modifyAttri(self,attri): 

 self.attri=attri 

 print("Attri: ",self.attri) 

class Female(Person): 

 女性类 

 def __init__(self,hobby): 

 self.hobby=hobby 

 print("hobby: ",self.hobby) 

 def getFamilyInfo(self): 

 print("Ten members in hers family.") 

c=Female("swimming")#实例化一个对象 

c.getFamilyInfo()#调用子类方法 

c.modifyAttri("SWIMING")#调用父类方法

hobby: swimming 

Ten members in hers family. 

Attri: SWIMING 

Process finished with exit code 0

下面看下子类调用父类构造方法：

3. override
