you are good ,Appreciate that but what is the difference b/n function and Class? and what is the d/f between (in function ) def __beach __: and def beach : ?

Good question. Let's use our beach example and lets say we want a script that will go through all the beaches in the world and pick out ones that might be fun to go to. Functions are just blocks of code that have a name. I can make any few lines of code into a function. Usually when I make functions, each one has a specific "task" that makes it logically separable from the rest of the code (so in my script i might have some functions like get_all_beaches which might have code that gets all the beaches in the world, then filter_beaches which might have code that filters through all of those beaches, etc.) You could technically just put everything into the script without the functions but it helps with organization. On the other hand, classes represent objects, so it's not really just "a chunk of code that we name". Instead, it's like saying "hey let's create something that helps us represent a beach". In my example, after getting all the beaches in the world, I would create beach objects for each beach just to represent them in a clean way. Then I can store name, location, water color, etc. as part of the object's properties instead of as a random dictionary. Does this make any sense?

And then for the difference between the functions within the class that are like __init__() vs something_like_this.. __init__ is a standardized python function for classes. Functions like this are actually called magic methods. When you create an instance of the object, python knows to run this function __init__(). In a similar way, if we have a method in the class __str__(), this actually would tell python how to make a string representation of the object so if we have cancun_beach = Beach('Cancun') and we do print(cancun_beach), it would print whatever the string representation is, so it actually prints cancun_beach.__str__()... Other functions are ones that you are defining and adding to the class. Take a look at these resources if my explanation isn't very good: www.geeksforgeeks.org/dunder-magic-methods-python/#:~:text=Dunder%20or%20magic%20methods%20in%20Python%20are%20the%20methods%20having,__%2C%20__repr__%20etc. www.journaldev.com/22460/python-str-repr-functions Hope this helps

I have always struggled to understand classes especially the use of "self". This is the best explanation i have come across so far and now i have a good understanding of classes. I'm actually surprised at how easy it is, almost feel stupid that i struggled with the concept for t6oo long. Thank you! Thank you!

I cannot thank you enough Kylie. You are a beautiful soul. I was two runtime errors away from dropping the class because I couldn't figure out Zybooks but you broke everything done so wonderfully it just made sense. So my future bachelor's degree is all thanks too you!!!

Watched almost all popular OOP videos and this one helped me understand it a whole lot more, thank you

so it seems as though video number 9 is when we take things up a notch. I might have to watch this one a few times as my brain currently feels like it did after i watched Inception for the first time haha

Kylie, I've just watched 5 videos on classes back to back and this was by far the best explanation.

Hands down one of the clearest explanations of basic Python on YT. Thanks so much for your vides Kylie

Excellent lesson! You really are a great teacher. Thanks once again.

Hi ! I am a monk. I have been learning coding to help the Tibetan astronomy science to preserve. I could have done some projects on it, and I am still on progress to accomplish. but because of lack knowledge on python I am stuck ..... I watch your videos , they are helping me to build up concepts.....Thanks

You motivate me to do better!!! I struggle with this simple concept!!!

Such an awesome explanation. Thank you so much you have helped me a ton with this difficult concept. I hope you find success teaching- amidst others I have seen- your teaching style is very easy to pick up and learn from right away. VERY awesome, very thankful!

I do not code and do not ever plan on it, but I watch all your vids!

your videos are very helpful. Thank you so much.

damn girl you go fast, I've gotta pause the video to catch up rofl. But you helped me heaps though very good examples you shown Thanks

Nice vedio i am from Bangladesh

Thank you Kylie

Love your videos! So clear and thorough! is the terminal app the same thing as the command prompt? and how do you paste that path in so fast? and maybe you have a video that is a brief intro to using the terminal app to run the code I write in vscode? never mind... figured it out on my own. Still love your videos! slowly working my way through all of them. started with PyCharm Community, mostly because it has lots of buttons, then moved to Mu, which I use with my middle school club, then downloaded vscode, which seems pretty intuitive. thanks for being so patient with all of us!

U are so talented ,indeed an inspiration to me!

Thank you for the video! When a parameter is passed to a class, why should the parameter be assigned to 'self.parameter' and an attribute be created? Isn't the parameter available throughout the class and given? Is it to assign some type of memory to the parameters?

Hey! I'm having some issues with the last bit of code at 11:43. Everything up until "print(cape_cod_beach.parts)" works just fine, but the second last line gives me an error: AttributeError: 'Beach' object has no attribute 'add_parts'. Very helpful video! Thank you so much!

Awesome video! How would you save this class as a separate .py file and import it into other notebooks? I've been trying....but name-errors all over....some functions inside the class are "not defined"......

Very nice explanation!!!

Loved the video! It helped a lot!

Kylie, when I execute this code in Pycharm (windows) I get what am not doing right?

thanks for the vid really helpful. Can I ask what is the purpose of the last 3 blocks starting in if __name__? thanks a lot and more power!

Thank you Teacher Kylie

Thank you Kylie.

Heyy Kylie, how are you doing. I'm a new subscriber of your channel and love the contents you have on. I am also a new learner of Python language. I wanted to know how i can be good at writing my own codes and what steps i should take from the basics. Thank youuu

Ahh your videos are so helpful! Coding is fun who knew?! Well I guess you did😂

Thank you queen ♥️♥️♥️

I love your channel Kylie :-D

Why do you run your program with the terminal app? Isn't it more efficient to just press "run" in the text editor?

could You please, explain me line 27 ?(;

But how don't use this for real world projects?

Nice!

mam can you tell me what is the use of __name__ ?

Great tutorials . I fpossible could you make tutorials for python app development too . Thanx . :)

Would the initialisation still work if we renamed __init__ to something else?

No, to custom initialize a class you need to define the code under the __init__ method

That part is basically saying if you’re directly running the script (ie ‘python3 main.py’) then you run that part under the if. Then you might ask, when would you not run the script directly? This is the case when we actually define maybe functions or classes in a script (let’s say this is helper.py) and then import them from another file (let’s say main.py). Well in helper.py, I might want to run some stuff to help make sure I’m coding the right thing, but I don’t want these to actually show up when I try running main.py. If we don’t have that if statement then when we run main.py we actually run whatever random code is in helper.py. But if we add the if statement, then we can import helper without running the random code under the if statement. Does that make sense? Good practice for making sure your code doesn’t print out random stuff when you have a ton of imports and files.

Hahahahah think of yourself as a “Person” object. We are all instanced of the Person object. In order to get the person’s name you do self.name for example which refers to that person’s self.... it tells the object to look at that specific instance and look for the attribute... does that make more sense?
