Thanks a lot for posting this, FCC! ❤️

I'm only 20 minutes in and already several concepts that were blurry before are now crystal clear to me. Excellent video!

For those who didn't understand the static method, def is_integer(num) = Our Function & num.is_integer = Built-in Function. is_integer() is a popular built-in function that checks if a floating number is actually an integer. As an example, 7.0.is_integer() will return True whereas 7.3.is_integer() will return False. So as to avoid confusion, let's just change Our Function name to def check_integer(num) 🙂✌

Only today and after watching this tutorial I understand "self" in python!

I'm only up to the 45 minute point so far, but already I am very grateful for this tutorial. Thank you so much!

00:04 Understanding object oriented programming is important for software developers. 07:57 Creating a method to calculate the total price of items 23:21 Understanding constructors and best practices in classes 31:11 Learned about constructor and working with different attributes 45:44 Using a for loop, we can print the names of all instances 53:38 Read CSV file and instantiate objects with class method. 1:09:32 Create a separate class named 'Phone' that inherits from the 'Item' class 1:17:02 Inheritance allows creating child classes that inherit attributes and methods from parent classes. 1:31:54 Create read-only attributes in Python using the property decorator 1:39:20 By adding double underscores to attribute names, access to those attributes is prevented outside of the class. 1:54:40 Encapsulation and abstraction principles are applied in object-oriented programming. 2:03:06 Inheritance allows code reuse across classes

This guy is amazing. He has taught me Selenium, Classes and I'm sure many more things in the future. Keep up the good work Jim, you're a beast!

I find myself especially loving the structure of this OOP tutorial, it comes from a Funtional programming aspect and gradually lead you into OOP with examples, as oppose to other tutorials where they directly introduce you to concepts like inheritence/settters etc.. This makes my understanding of OOP much more clearer and structred. Big thanks to FCC and the lecturer!

1. In the run validations to arguments part, if you aren't getting an error when you use an integer as the name, type in assert type(name) == str. This will not accept anything other than an integer as the name. 2. Make sure you have no spaces between the list in the items.CSV file. Its a minor thing but gave me a headache since I couldn't get past that for a while. Then do the normal int(item.get()) then it works fine. Finally most of the issues I encountered were as a result of not looking at the code long enough. If you encounter a problem, make sure to re watch the part where he DOS it and make sure you got it correct. This happened to me at the Len part and a few others. Finally if you encounter s problem not stated here, then copy the error and paste it in your browser. This shows a stackoverflow page first where you can figure out what's wrong. Hope this helps you and you don't have to go through the headache I did when solving those lol

Just completed the whole video and this is hands down the best object oriented programming course I've ever come across. I've been trying to understand what exactly OOP is all these days by reading blogs and going through different tutorials. Nothing gave me as much clarity as this video did. Thanks a lot for the great work and for giving this out for free!

Loved It! I have been in a 4-Year CS program and learned the OOP concepts in different lectures. Probably this one is the best among all the lectures/tutorials I have taken for OOP till now.

Sir, thank you for this absolutely fantastic run through of object oriented programming. I was struggling with some of these concepts in using python to build a Django website, but this tutorial cleared up a TON of information. Very well done, I along with 100K+ others, are incredibly grateful that you took the time to put this together to clear up some confusing concepts.

I've been learning and coding Python for a little over a year and have never fully understood the __init__ method until I saw this video. You rock!

Best explanation on OOP on UKposts. He doesn't skip anything. It finally makes sense 😊

It's really really useful for begginers like me to have a tutorial builded from the scratch, instead of just downloading code from an external source and all of a sudden try to understand whats happening on those 50 lines of code. Thx

This tutorial was hands-down the best I've ever watched regarding the essential concepts of object-oriented programming. You clarified so many of my unanswered questions. Thanks a million!

Less than 10 minutes into the tutorial and I understand what the class is. Some of these free tutorials teach better than actual courses we pay money for

Best intro to OOP so far. Explained so well. Thank you so much for this excellent course!!

1:08 "is_integer" is a float method, since the name of the written method and the float method name are the same, there is a misunderstanding as if the method is calling itself again. It was a confusing example. It took me a long time to understand and figure out what was going on. 7.0.is_integer() return True :)

This is the most comprehensive and friendly tutorial on Python OOP I have seen so far. Thanks for this Jim

Very practical and understandable take on OOP in python. Greatly recommended to people with a beginner level knowledge of python and need to add OOP to their python tool kit.

Wow, he wasn't lying . He really explains it well; you wouldn't need another tutorial .

Simply perfect ! Though I was doing revision but it helped me in learning the concepts easily.

Great course! This took me from having a basic knowledge of OOP to understanding the logic of how it all works much more! Excited to keep going deeper with these topics!

Absolutely fantastic. Definitely, the best introduction to Python OOP I have seen so far.

20 mins in and so many concepts are made clear and so quickly and efficiently. Thanks the instructor and FCC.

The practical way of explaining and the gradual pull into the concept was awesome. I am finally understanding. Thank you so much

By far the best OOP python I ever found, clear, easy to understand, ensure that everything is crystal clear.

For anyone who also installed the csv plugins but the "Table Editor" button didn't appear: you have to go to File | Settings | Editor | File Types, go to "Text", and then add *.csv to that file type. Confirm it and you're good to go. =}

Great explanations! I like that you clarified certain aspects of OOP that are hardly ever mentioned in other OOP courses. Thank you!

Thank you for such a clear and detailed tutorial! This helped deepen my understanding of these concepts. Absolutely worth watching!

This is, by far, the best tutorial I've watched in a long time. Man have you got didactics for days. Congrats!

I have to admit that when I heard the presenter's thick accent, I was worried, but I've just finished the entire video, and I must say that this was an EXCELLENT presentation. Turns out dude is very easy to understand. Speaks clearly, slowly, concisely, and precisely. Doesn't just superficially intro you to each topic--he really takes the time to explain the principles. A+! THANK YOU for taking the time to create and share this with the world! This was basically my into to object oriented programming and I really do feel like I've learned a whole lot after this 2+hr video!

A perfect course if you know the general concepts but they are not clear enough. Electrifying! Good Job

The whole concept of OOP is explained in a structured and easy to understand way. I am a beginner and learnt a lot from this. Looking forward to learn more from your videos . Thankyou

ABSOLUTELY FANTASTIC!!! Thank you so much Jim. I followed this tutorial line by line and learnt so much. I owe you this new beginning of my life.

The thing that most tutorials miss is an indepth explanition of the logic of how things work. Fortunately, this tutorial does not skim on explaning the logic and also giving examples of use cases. Thanks Jim!!!

Great course, I liked the order of subjects so everything made sense while learning OOP. Many thanks!

Thank you so much. I've been having such a hard time for hours trying to understanding classes and methods. This was perfect.

Great tutorial. I was a bit confused when you built your staticmethod is_integer at first. But then I realized float has a method built into it also called "is_integer", which will return true if the float ends in .0. Once I figured that out it made sense to me. Hope this helps someone who is confused by the same thing

I was trying to learn oop concepts for a very long time and I was having a very hard time learning this then found this video, still in the 1st chapter __init__ and most of the things I was having hard time with got very clear. Thanks for this, I will always remember you. FCC is doing great work finding these high quality videos .

He is great explainer bring him back again on this channel !!! ✨👏🔥💯

finished in one sitting after finishing a similar course on datacamp and I understood everything perfectly. thank you so much man

A very enjoyable comprehensive lecture, the study material is delivered in a clear and adequate manner

Thank you very much, For the last month I was wandering on the internet to understand OOP, with no success now it is crystal clear. Une fois encore, merci

Thank you so much, I was looking forward for such a course

Learned a lot from this course, helped me to understand OOP better. Thank you so much, Jim and FCC.

this made more sense to me than any other OOP tutorial I have ever watched. Thank you so much

OMG!!! I am finished only 23:30 and this so amazing!! Looks like this video is going to be in my permanent youtube storage vault!:):) I already have decided to watch it more than once. Already cleared up a few critical concepts that I was struggling with. You have an amazing explanation power.

man it's so amazing. You are so good at explaining. Thank you soo much for get me out of the confusions. ❤️🙏🙏

Thank you for this tutorial. I've participated in a number of courses and by far this is the best object oriented programming course I've seen.

OOP has always been a sticking point for me, but thanks to this in-depth tutorial, it is all starting to make sense. Thank you FCC for posting this!

The is_integer function name almost confused me. is_integer is a method on its own in python so I thought you were calling your defined function inside the function itself. I'm clear now, made me research more and I'm happy about that. An awesome video by the way, I've mastered OOP basics from this. Thanks so much.

This was insanely helpful. Easily understood, clear examples.

Thank you so much for this amazing tutorial! I’ve only been learning python for a few weeks but this helped me understand many core principles of OOP. Not going to lie, a little of this was still over my head but I’ve saved this video so I can watch it a few more times of the next few months. Thanks again

i am a self taught programmer and previously ive tried to learn linked list and got totally lost and confused. i was told i should learn OOP first. my friend had a syllabus for a OOP class, but i didnt want to spend threee months on it so i went onto this video and i learned so much. took about 3-4 days digesting information. you broke down the steps in a way thats easy to digest and remember. although this topic has a lot of information, now i see all i need is to practice these concepts often and ill get it. you have explained in two hours a whole entire syllabus that would take aquarter, which is about 3 months. thank you so much

Я просмотрел все 2 часа этого курса, и научился читать код, и понял общие правила ООП. То что раньше было сложно понять, понимать стало гораздо проще. Вместо повторения \ дублирования кода, можно написать код лаконично, и он будет выглядеть очень аккуратно, это очень круто. Мне жаль что на просторах интернета, на Русском сегменте, вот таких полных курсов очень и очень мало, но найти ваш канал было просто волшебно. За 2 часа, начиная от самого простого, переходя постепенно к пониманию того что происходит, с указанием что откуда наследуется и передается, в общем я очень рад что эта информация очень полезна для меня. Осталось только научиться делать это самостоятельно, и продумывать код и его логику. Жаль у нас не было уроков программирования, да и преподаватели обычно не умеют доносить информацию понятным и простым языком, объясняя сложные вещи простым языком. Благодарю вас.

The explanation on this tutorial is very clear and to a point. I understood lots of things, which was a bit of a magic before this video. Thank you very much and keep posting fruitful videos

This is gold. Jim is awesome! For sure in my top 3 best teachers. So easy to understand.

20 minutes in and the gentleman has clarified all the questions I had regarding OOP. This makes so much sense.

Amazing OOP training, alot of concepts clear by now for me

Thank you very much Jim, this helped me a lot to understand OOP

Awesome video! I'm half-way into it, and I've already learned more than I learned in an entire OOP class on another platform! Thanks so much!

THANK YOU for making your font size large enough to read on a tablet. So many channels don’t do this.

1:08:52 The name "is_integer" was a bit confusing because same method exists for 'float' class so in first IF statement num.is_integer() has nothing to do with the is_integer function that has been created in this code. That is_integer() method is pre-defined for the float class and that is only there to check if the num is a float or not and returns TRUE.

Watching at 0.75 X. This is by far the best tutorial on OOP. Hands Down.

What an excellent tutorial! Amazing man. You are a wonderful teacher. Hats off to you. God bless you!

I was Struggling to understand the concept of Class through tutorials, but this tutorial helped me to really understand well. Thanks a lot!

What a brilliant course! Thank you :)

The best OOP video ive ever seen. I would have failed without you LMAOO my profs could never compare.

This is a top notch crash course. Simple and short to start building stuff. Thank you!

I'm now halfway through, but this is an excellent video for learning OOP, always struggled with it, but this one is just great, so thanks a lot!! Learned so much from it. EDIT: I've completed the whole video by now - what a journey, thank you so much for this course!!

This is just the thing i was looking for... Thank you very much ❤

God bless this man 🙏

Theory intensive but very crisply explained! Excellent video!

Such a lovely way to explain the OOP. Practical project based examples makes it even more interseting. Thank you

waiting for this from a long time , thanks :)

Hey, For anyone here who might be struggling with a 'NoneType' error when trying to call ur CVS file and convert it into a list, go back and make sure there are no spaces in between attribute names. Remove all extra needed spaces example: should be: name,price,quantity not: name, price, quantity

Now i am in this video for 50 minutes and I got to say, this video is golden. This video is like if you want to digest 1000 pages of content in one video. Truly Awesome.

Literally the Best OOP tutorial I've found. Thanks so much. Subbed to both.

Thank you so much for this extremely useful tutorial.

Just what I needed ❤️

I have already watched and downloaded your videos on my computer. A great course thank you Jim

I finally completed these Object oriented of python, i would recommend every body to watch these to have a good grasp of concepts

Learned so much from single video thanks alot 👏✨💯🔥🔥

I think naming that is_integer(num) method was wrong because already there exists an inbuilt method called is_integer() that can be called upon floats.... All this while I was thinking of recursion....

It's an excellent video with a clear-cut explanation for a learner like me. I have watched many videos for understanding these concepts finally this one made me understand them clearly.

Really helpful tutorial, thank you so much. I really liked the fact that Jim practically demonstrated everything first and then explained the theoretical principles afterwards :)

Thanks!

Hi, Thanks for posting !!! , there is a catch at least in unix ( !!! items.csv file has spaces in front of columns price, quantity which triggers an error : price=int(item.get('price')), TypeError: int() argument must be a string or a number, not 'NoneType')

this is the best OOP video i have ever watched. i also got confused with the concepts used in OOP such as init,self and how to use them and what is the actual mean behind these concepts now has been revealed. thank you very much for your great content.

This guy is very good with explaining and teaching. I really learnt a lot from about OOP that had been confusing to me. Thank you so much

I'm fluent at OOP in Java and now I feel stuck when doing it in Python lol

Shalom!

Thank You @JimShapedCoding 🙏 As you said at the beginning of the tutorial, this is gonna be my last search for OOP. I was looking for someone like you [my whole life😀] to explain the OOP to me. Most tutors just write the codes and never explain what is self or what is the point of using the classes and... You showed in detail why I should do it, and how I should do it. I can't learn anything off by heart, thus, I need to understand everything, so I could use it in the right way, and you man, helped me to understand. Thank You.

I've learned so much from this video, I really feel this has taken me to the next level of my knowledge in Python. Thank you!!

I prayed to God for this

At 1:32:33 I got this error when trying to write: print(Item.instantiate_from_csv()) print(Item.all) error :in instantiate_from_csv with open("items.csv", "r") as f: FileNotFoundError: [Errno 2] No such file or directory: 'items.csv'

Thanks for this course! It's been really useful as a complement to my Software Engineering studies.

watching it now 2 yrs after it was published. Super amazing. Thanks buddy.
