Having knowledge is different from being able to share it in a clear, concise manner and this is where Navin reddy sir comes in. Luckiest is the one who gets a teacher like you in every subject.
This is genuinely one of the best videos out here for OOPs concept in Python. Everything was taught was sooo freaking well, with real life and examples and code and it's explanation, amazing, great work man!
Man!!!! I never knew I would understand at least the basics of OOP one fine day!! And that day is today... I cannot thank you enough, what a brilliant teacher you are. Your examples are amazing and I am really happy to have watched your videos today. Liked and subscribed. :)
Thank you, sir. You don't teach stories, you come directly to the point that is actually needed. I learned so much from your Java programming videos. Stay blessed
There's something really cool about the fact that the dev community as a whole, just decided to ignore the fact that the acronym for Python Object Oriented Programming is POOP
thanks to you weeks of my hardwork has finally paid off....i didnt got good teachers in college none anyone online explaining all these stuffs in detail..kudos..thankyou very much
I am surprised that I sat through the entire video in one sitting. Can't remember last time I did that! even for a movie. In all honesty, good explanation of the concepts, I am excited to learn more.
you're legend, thank you for the amount of effort! deep understanding comes from practice but you've already put all the deep stuffs so we are already ahead!
I was struggling to understand OOPs quite for some time, This session gave me clear idea on OOPS ofcourse lot more to learn.. but kudos to Navin. Thankyou so much!!
the 1st time i saw this i learnt some then i went across many videos and made the concept clear now im again back here. All the topics are discussed here.and now things are crystal clear.
Sir, as I always say about you that you are totally awesome. Your videos have so much stuff that a person who did not know anything about coding can also become a legend in coding. Thank you for making such great videos. Thank you very much sir.
Hello, sir you are one of the biggest programmer in the world sir I have just completed your video it is one of best video on the concept of oops. one day you will become big programmer Thank you very much for all of these
I had pursued an online course ( worth 8500INR )from one such online coding teaching company and was literally crying because I was unable to understand OOPS at all. I watched this video and let me tell you, I am Very very confident in OOPS. I will also look for some more videos on this channel as and when needed. Thank you, sir. Time needs teachers like you who deliver such content for free. Thanks a lot!!
Finally a proper tutorial. For some reason other RUclipsrs act like they can explain this topic in 5 minutes. While in reality this is a complex topic especially for beginners. So, in those 5 minute tutorials you might have a bit of a grasp of what you're doing, but you're still clueless when you are on your own. Thanks for the tutorial! It was very informative!
i know people with same kind of knowledge as this instructor, But he has got what it takes to be a good instructor, he knows how to do it right. kudos to the way you teach stuff. hats off guru.
Simple and Very Clear Understanding...Since a long time I was struggling with OOPS concepts but today, it got cleared mostly and I hope I will clear my interview as well for which I'm preparing ;)
Awesome Video ! 🙏 In Method overloading (1:27:00) , student 1 and student 2 value added so for student comparison it can be like below def __add__(self, other): m1 = self.m1 + self.m2 m2 = other.m1 + other.m2 s3 = Student(m1, m2) return s3
This guy is simply awesome. He explained the topics as clear as crystal and better than many paid tutors. he In such a small video packed amazing treasure of concepts and basics of OOP. Love this guy. completed this video in 3 days. such a pleasant experience. I actually felt nostalgic at the end of the video that its over. Thank You Naveen Bhaiya. I love you and your work is phenomenon.
I written same that that wrote but __init__ method is not getting call automatically . I'm not getting output of __init__ method . Please can u help me
I havent started watching this but I have a good feeling about this after watching your django for beginners am really grateful that I have found your channel
this helps me a lot!! I took a paid course on Udemy but couldn't understand OOP! but watching this video really helped me to understand the OOP concepts. CAN"T THANK YOU ENOUGH!
at 56:16 where you have defined class inside class calling the instance as such will fail , if your init method inside class has arguments ( TypeError: __init__() missing required positional arguments) .Rather a better way of calling would be s1=..() .This works universally
Hi! Thanks for such a detailed lecture on OOP concepts using python. I found it really useful and wanted to say you thanks for all the efforts you put. Because earlier I got just very abstract level touch of classes but concepts like inheritance, class/static variables, instance variables, Class Methods, Instance Methods, Static Methods, Polymorphism, Duck typing, Operator overloading, Method Overloading techniques in Python and method Overriding. I learned a lot and really wanted to say you thanks for such detailed and in depth lecture which actually was different from others available on RUclips and was very informative.
OMG, This video was very helpful. I came from java background, and was confused about the fact that why all methods in Python has "self" inside their parameter, even if we are not passing anything. But, now it is clear to me. Thank you so much :))
Really wonder man I am very pleasure to watch it. Real time examples make me to understand more Clearly. Thank you so much. Please make more videos on SQL also. 💯✌
Believe me Sir, I have watched till now 10-12 different YT channels for understanding this topic, but you made it soo much easy for me to understand. TYSM.....
At 1:38:20, if you are like me and create another method just to test out if you'll get an error or not by typing this: def sum(self,a,b,c): s = a + b + c return s You will find out that it works. The only problem here is that now your first method will stop working. This one: def sum(self,a,b): s = a + b return s It surprised me that it worked and I thought that because I had the latest version of Python that the creators of Python might've changed things, because it was working. But they haven't. The first method doesn't work and gives and error. And only the second method works when you do it. So, don't do it. I got the same error shown at 1:38:45.
This was a great video that puts together all the fundamentals of OOP with python. As a learner I would like to know more about the MRO concept, how to overcome it, etc
I'm looking for React tutorial of this level. Amazing work. This is the first programming related channel that I've subscribed to. Waiting for React tutorial 2019! Melodious respect!
Dear , Navin Sir, Thank you So Much.for this Amazing Video .Your Real World Examples are So Good . Animations make this tutorial super helpful .Because Object Oriented Programing is always about real world matters .I wish to thanks all peoples in Telusko team for creating such a High Quality content and Tutorial and all the Very Best .
Excellent video, I sat through the whole video. It was a good idea to create a single video for OOPS and separate the part from the rest of the Python tutorials.
Anil A Yes, you can change the value of class variable using the object, but that won’t change the value of the variable for other objects. As in your example, the wheels of car1 was changed to 5 but that of car2 is still 4 and will be 4 for the class as well as any other object you create.
In operator overloading: def __add__(self,other): s1 = self.m1 + other.m1 s2 = self.m2 + other.m2 s3 = Student(s1,s2) return s3 This one worked well for me!
You are the best teacher ever sir......Can't explain my happiness .. Finally i too understood all oops concepts today.. Thank you somuch for all your efforts sir...
Please explain a simple real time example with calssmethod, staticmethod etc,, which really tells the need for classmethod and staticmethod rather than printing some message.
Thanks for uploading this video. Anyone who has watched the video knows how awesome it is . Now I comprehend OOP very well but can't comprehend my gratitude.❤
Kudos to this guy. I would give this guy 1000 likes if i could....
This guy just literally cleared all my doubts regarding OOPS in Python...

Hi Naveen,
I am able to see the change of class variable while changing using object instead of class. Is this expected?
Code:
class Car:
# Whatever variables defined here are called class variables
wheels = 4
mirrors = 3
def __init__(self):
# Whatever variables defined here are called instance variable
self.company = "Renault"
self.milage = 20
self.gear = "Automatic"
car1 = Car()
car2 = Car()
print(car1.wheels, car1.company, car1.milage, car1.gear)
print(car2.wheels, car2.company, car2.milage, car2.gear)
car1.company = "BMW"
car2.company = "Maruti"
car2.gear = "Manual"
print(car1.wheels, car1.company, car1.milage, car1.gear)
print(car2.wheels, car2.company, car2.milage, car2.gear)
car1.wheels = 5
print(car1.wheels, car1.company, car1.milage, car1.gear)
print(car2.wheels, car2.company, car2.milage, car2.gear)
Output:
(4, 'Renault', 20, 'Automatic')
(4, 'Renault', 20, 'Automatic')
(4, 'BMW', 20, 'Automatic')
(4, 'Maruti', 20, 'Manual')
(5, 'BMW', 20, 'Automatic')
(4, 'Maruti', 20, 'Manual')
Anil A Yes, you can change the value of class variable using the object, but that won’t change the value of the variable for other objects. As in your example, the wheels of car1 was changed to 5 but that of car2 is still 4 and will be 4 for the class as well as any other object you create.
One of the best lectures available on Python OOPs in Hindi on youtube. Thanks You Sir.
In operator overloading:
def __add__(self,other):
s1 = self.m1 + other.m1
s2 = self.m2 + other.m2
s3 = Student(s1,s2)
return s3
This one worked well for me!
you're adding m1s and m2s of different students tho.
finally i found a way to understand OOPS........thank you sir..ur work is just awesome
