Person 이라는 부모클래스 /

Person

을 상속받은

Baby 클래스를 선언

class Baby(

Person

):
def eat(self):
return "bottle^^"
def play(self):
return "burning!"
부모클래스에

eat 이라는 함수를 오버라이딩

class Baby(

Person):

def eat(self):

return "bottle^^"

def play(self):
return "burning!"
Person 이라는 클래스를 선언하고, 
Baby 클래스는 Person을 상속받는다.
ptr 은 Person 인스턴스, zzazzan 은 Baby 인스턴스를. 그리고

eat이라는 메소드를 호출

해보자.
Baby 에 맞는 eat함수 결과가 나왔는지 확인하면 끝.
[a@tpl-master ~]$ cat Person.py 
#!/usr/bin/python
class Person:
eyes = 2
nose = 1
mouth = 1
ears = 2
def eat(self):
return "nam~ nam~ "
class Baby(Person):
def eat(self):
return "bottle^^"
def play(self):
return "burning!"
ptr = Person()

print ptr.eat()

zzazzan = Baby()

print zzazzan.eat()

,'\t', zzazzan.play()
[a@tpl-master ~]$ python Person.py 
Tae-Lyn( nam~ nam~ )
Zza-Zzan( bottle^^ ) burning!
[a@tpl-master ~]$ cat Person.py 
#!/usr/bin/python

class Person:

eyes = 2
nose = 1
mouth = 1
ears = 2

def __init__(self, name):

self.name = name

def eat(self):
return

self.name +

"( nam~ nam~ )"

class Baby(Person):

def eat(self):
return

self.name +

"( bottle^^ )"
def play(self):
return "burning!"
ptr =

Person('Tae-Lyn')

print ptr.eat()
zzazzan =

Baby('Zza-Zzan')

print zzazzan.eat() ,'\t', zzazzan.play()
연습. Kim씨네 부모클래스를

상속받은 Lee씨네 클래스

를 만들어 보기, 그리고

연산자 중 + 을 오버로딩

해보기
[root@tpl-master python]# cat inheritance.py 
#!/usr/bin/python
class HouseKim():
lastname="Kim"
def __init__(self, name):
self.fullname = self.lastname + name

def __add__(self, other):

return self.fullname+ " live in with " +other.fullname
def born(self, where):
return self.fullname+ " was born in " +where
aj = HouseKim('A-Jung')
print aj.born('Seoul')

class HouseLee(HouseKim):

lastname="Lee"
def liveIn(self, where):
return self.fullname+ " live in " +where
hr = HouseLee('H-Ryeon')
print hr.born('Seoul')
print hr.liveIn('Pusan')

print aj + hr

결과는..
[root@tpl-master python]# python inheritance.py 
KimA-Jung was born in Seoul
LeeH-Ryeon was born in Seoul
LeeH-Ryeon live in Pusan

KimA-Jung live in with LeeH-Ryeon
