Inheritance:
============
acquiring of the properties (attributes & methods) from one class to another class is called as an "Inheritance".

or

Inherit the data and methods from one class to another class is called as an "Inheritance"

ex: 

class Bank:
	def __init__(self,roi = 0):
		self.roi = roi
	
	def homeLoan(self):
		self.roi = 0

class ICICI(Bank):
	self.roi = 10
	homeLoan():
		self.roi =7

class Axis(Bank):
	self.roi = 12
	homeLoan():
		self.roi = 7.9

=====================
Types of Inheritance:
======================
1) Single Inheritance
======================
	there is only one parent class and only one child class
	==> the child class can acquire all the data from the parent class
	but the parent cannot acquire the data from its child class.

class Parent:
    a = 121
    b = 1.001
    def sum(self):
        print("The Sum is = ",self.a + self.b)

class Child(Parent):
    p = 112
    q = 1.112
    
    def sub(self):
        print("The Difference is = ",self.p - self.q)

pobj = Parent()
print(pobj.a)
pobj.sum()

cobj = Child()
cobj.sub()
cobj.sum()
print("Parent Class Attributes are:")
print(cobj.a)
print(cobj.b)
print("Child class Attributes are:")
print(cobj.p)
print(cobj.q)

# print(pobj.p)

==========================================

2) Multiple Inheritance
=======================
	Single child class can acquire the data and methods (properties) from multiple independent classes.

class Parent1:
    a = 121
    b = 111

class Parent2:
    def Power(self,a,b):
        print("Power is = ",a**b)

class Child(Parent1,Parent2):
    p = 1221
    q = 1.2221
    
    def sum(self):
        print("The Sum is = ",self.p + self.q)
        
ch = Child()
ch.sum()
ch.Power(3,4)
print("The Parent1 Attributes are = ")
print(ch.a)
print(ch.b)

p1 = Parent1()
# p1.sum()
# p1.Power(2,5)

==================================================

3) Multilevel Inheritance
=========================
	The features of base class and derived class can inherit to another derived class.

class A:
    a = 10
    b = 20

class B(A):
    p = 100
    q = 200
    
class C(B):
    x = 111
    y = 222
    
cobj = C()
print("The Data of itself = ")
print(cobj.x,cobj.y)

print("The Data from B Class = ")
print(cobj.p,cobj.q)

print("The Data from A Class = ")
print(cobj.a,cobj.b)

bobj = B()
print("The Data from B Class = ")
print(bobj.p,bobj.q)

print("The Data from A Class = ")
print(bobj.a,bobj.b)

# print(bobj.x)
==============================================

4) Hierarchy Inheritance
=========================
	==> single parent class
		with multiple independent child classes
	==> all child classes can acquire the data from parent class equally.

class A:
    def greets(self):
        print("Hi")

class B(A):
    def m1(self):
        print("Good Morning.")

class C(A):
    def m2(self):
        print("Good After Noon.")

class D(A):
    def m3(self):
        print("Good Evening.")
class E(A):
    def m4(self):
        print("Good Night.")
        
bobj = B()
bobj.greets()
bobj.m1()
# bobj.m2()

cobj = C()
cobj.greets()
cobj.m2()

dobj = D()
dobj.greets()
dobj.m3()

eobj = E()
eobj.greets()
eobj.m4()

===========================

5) Hybrid Inheritance
======================
combination of above any type of inheritance

Single + multiple
multiple + multilevel
hierarchy + single + multiple 

class A:

class B(A):

class C:

class D(B,C):
