#Add a year parameter, and pass the correct year when creating objects.
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
class Student(Person):
def __init__(self, fname, lname, year,byear):
super().__init__(fname, lname)
#self.graduationyear = year
self.yd=year
self.birthyear=byear
x = Student("Rahul", "Shinde", 2019,2000)
print("First Name:",x.firstname)
print("Last Name:",x.lastname)
#print("Graduation Year:",x.graduationyear)
print("YD Year:",x.yd)
print("Birth Year:",x.birthyear)
Output:
First Name: Rahul
Last Name: Shinde
YD Year: 2019
Birth Year: 2000
-------------------------------------
#Adding new properties for the child or derived class.
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
class Student(Person):
def __init__(self, fname, lname):
super().__init__(fname, lname)
self.graduationyear = 2019
self.bg="AB+"
x = Student("Ram", "Shinde")
print("First Name:",x.firstname)
print("Last Name:",x.lastname)
print("Graduation Year is:",x.graduationyear)
print("Blood Group:",x.bg)
Output:
First Name: Ram
Last Name: Shinde
Graduation Year is: 2019
Blood Group: AB+
--------------------------
# Use the super() Function
# Python also has a super() function
# that will make the child class inherit
# all the methods and properties from its parent.
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
class Student(Person):
def __init__(self, fname, lname):
super().__init__(fname, lname)
x = Student("Rahul", "Shinde")
x.printname()
# By using the super() function,
# you do not have to use the name of the parent element,
# it will automatically inherit the methods and properties from its parent.
Output:
Rahul Shinde
-------------------------------
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
class Student(Person):
def __init__(self, fname, lname):
Person.__init__(self, fname, lname)
x = Student("Rahul", "Shinde")
x.printname()
Output:
Rahul Shinde
----------------------------
# Create a Child Class
# To create a class that inherits the functionality from another class,
# send the parent class as a parameter when creating the child class.
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
#Use the Person class to create an object, and then execute the printname method:
fn=input("Please enter first name:")
ln=input("Please enter last name:")
x = Person(fn, ln)
x.printname()
class Student(Person):
pass
y = Student("Rahul", "Shinde")
y.printname()
# Note: Use the pass keyword
# when you do not want to add any other properties or methods to the class.
Output:
Please enter first name:Ganesh
Please enter last name:Shinde
Ganesh Shinde
Rahul Shinde
---------------------------------------
# Python Inheritance
# Inheritance allows us to define a class
# that inherits all the methods and properties from another class.
# Parent class is the class being inherited from, also called base class.
# Child class is the class that inherits from another class, also called derived class.
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
#Use the Person class to create an object, and then execute the printname method:
fn=input("Please enter first name:")
ln=input("Please enter last name:")
x = Person(fn, ln)
x.printname()
Output:
Please enter first name:Rahul
Please enter last name:Shinde
Rahul Shinde
---------------------------------
# The pass Statement
# class definitions cannot be empty,
# but if you for some reason have a class definition with no content,
# put in the pass statement to avoid getting an error.
class Person:
pass
Output:
-------------------------------
# The self Parameter
# The self parameter is a reference to the current instance of the class,
# and is used to access variables that belongs to the class.
#
# It does not have to be named self ,
# you can call it whatever you like,
# but it has to be the first parameter of any function in the class.
class Person:
def __init__(myobject, name, age):
myobject.name = name
myobject.age = age
def myfunc(abc):
print("Hello my name is " + abc.name)
print(abc.name," your age is",abc.age)
p1 = Person("Ram", 36)
p1.myfunc()
#Modify Object Properties
p1.name="Rahul"
p1.age = 40
print(p1.name,"is your changed name and",p1.age,"is your modified age!!")
#-------------------------
# Delete Object Properties
# You can delete properties on objects by using the del keyword:
# del p1.age
# print(p1.age)
#del p1.name
#----------------
# Delete Objects
# You can delete objects by using the del keyword:
del p1
Output:
Hello my name is Ram
Ram your age is 36
Rahul is your changed name and 40 is your modified age!!
