Python Inheritance

Object Oriented Programming provide a feature of inheritance.Inheritance is a process to create new class which acquires the properties of existing class with some changes.

class new_class_name(old_class_name):
statement 1
statement 2
statement 3

Python Inheritance Example

class One:   
	def a(self):  
	  print 'Hello...'  
class Second(One):     
   def b(self):  
	  print 'How Are You...'  
d=Second()  
d.b()  
d.a()  

output:
Hello...
How Are You...

Python Multilevel Inheritance

Multilevel inheritance is also possible in Python.

class First:   
	def a(self):  
	  print 'Hello...'  
class Second(First):  
   def b(self):  
	  print 'How Are You...'  
class Third(Second):  
	def c(self):  
		print 'Where Are You From...'  
d=Third()  
d.a()  
d.b()  
d.c()  

output:
Hello...
How Are You...
Where Are You From...

Python Multiple Inheritance

Python supports multiple inheritance too.
