Python Tutorial - 18. Inheritance

In today’s python tutorial we will discuss “inheritance”. The video will give insights regarding what is an inheritance, how to implement inheritance in python, how to derive a class from another class, how to create objects of class and the benefits of inheritance.

Topics that are covered in this Python Video:
0:00 Introduction
0:13 what is Inheritance
2:05 Implement Inheritance in python
3:01 derive a class from another class
5:29 create objects of class
9:50 benefits of inheritance (code reuse, extensibility, readability )

Wow, thank you so much!

This is the best I've seen for a beginning introduction to OOP! I am a self-taught programmer, and grasped everything up until this point (and started writing my own programs already). I could not understand classes with the other videos, but thanks to you, I finally got it. Subscribed! :)

Edit: "other videos" as in, other youtubers' videos haha

[ketankulkarni]

The first thing I do whenever I start the video is to give it a *Like*. I am afraid of forgetting to give a thumps up for each video of this channel.

[ramchandersahu]

you need more views man!!
you are great

[sachinshrestha]

Hello sir I have opted for btech IT and I am watching your videos for last 15 days on Python data analyst and I amjust loving it . i request you to upload video on data structures and algorithms please sir

[Mykelboachie]

Great tutorial. Just found this. Keep up your good work

[LuisMan]

Thanks you for all. !!!! it´s the best video that i found about inheritence!... I will follow you !

[iheanyionwubiko]

thank you for this simple yet effective tutorial.

[prudvinayakgugulothu]

Nice explanation with real-time examples and with general English

[siddharthupadhyay]

Simplicity is the highlight of this video tysm sir

[a.subashsethuraman]

concept clear
very usefull
thank you for giving this video

[BeYakko]

at 5:21 is the perfect example on why you should not copy paste your code. specially if you're a beginner.

Thanks for the great tutorial so far, i'm almost there (end of the playlist) ;--).

One question, lets say we want to give vehicle its own constructor, e.g. outsource the property wheels. How do we call both constructors properly?

class Vehicle:
def __init__(self, numWheels):
print("I'm vehicle")
self.wheels = numWheels

def general_usage(self):
print("general use: transporation")

class Car(Vehicle):
def __init__(self):
print("I'm car")
self.has_roof = True

def specific_usage(self):
self.general_usage()
print("specific use: commute to work, vacation with family")

class MotorCycle(Vehicle):
def __init__(self):
print("I'm motor cycle")
self.has_roof = False

def specific_usage(self):
self.general_usage()
print("specific use: road trip, racing")

c = Car() # how do we pass numWheels?

Good


Please add more videos on OOPs, abstract class, abstract method etc.

[febinjose]

sir can you post a video describing why we really need class concept, with an example coded using class and without class

[kostasnikoloutsos]

Thank you a lot.Here is my first program.
#In how many days we will change year
import datetime
class Dateremaining:
def __init__(self):

def result(self):
year=datetime.datetime(2018, 1, 1, 0, 0, 0)
self.difference=year-self.ct
return self.difference
Object1=Dateremaining()
print Object1.result()

what is the name of music which is being played at background, is so good

[kushichittimireddy]

why is the self written inside parenthesis provided, i mean what is its role?

[gargisingh]

Hi Sir, can you take one tutorial for scripting on Class and inheritance for any real life use case just like how you did Data Analysis using PowerBI. I mean how to understand the use case and then how do we start writing code for that use case which involves class and inheritance in it .

[rthu]

This also covers polymorphism but self I think is correlated to the instance of the class not the class.

[Mahesh-mfuw]

How to call the properties wheels and roofs?
