Amazing and clear tutorial, thanks for taking the time to explain in detail, it help me better understand some concepts I though I knew, thank you
hmmm... that was gay. Good
Aw hell naw bro paid 500 bucks for a free tutorial wad da hail
@@cheeseburgerinvr that is mexican dollar = 0.05 USD => 500MX$ = 10U$D. so don't worry brother it's not a big amount.
@@_Wrayor 500 pesos are like 25 bucks
@@cheeseburgerinvri mean if you make the money why worry? I wish I can spend without looking so my goal is to be very good at programming the thing I love to do.
When your mind gets completely blown 53:00, realizing that you can take a feature from one object and literally pass it to another! Super powerful. And amazing content!
New skill unlocked: OOP
THANK YOU!!!
This is the best Python OOP I've ever read or seen. I was stuck in procedural programming style for decades (software is not my profession). With procedural programming it always felt like hitting a wall when writing bigger programs. I've tried switching to OOP a few times before, and failed.
Followed your tutorial over the last two days, did the exercises, and now it finally all makes sense. You helped me to step to the next level, and I'm very grateful for that, thank you!
:o)
i think its one of the best oop guides for begginers out there. Very good visual explanation, people often forget that begginers have no clue what is going on and any form of visual explanation(other than code obviously) is extremely helpful
I watch so many videos to understand the concept of "self". This is only one where it has actually been explained properly. Thank you!
I am just learning classes and oop in python. I am just about coping but this has helped a lot. I love how you introduced classes without immediately using 'self'
Your content is always fantastic. Sharing this with a few friends who are just getting started!
I'm half way through my Bacherlor-studies in CS and since I didn't get a goold hold of OOP in the beginning of my studies, at this point I am really getting in difficulties as the programs get bigger. I was already wondering if I need to go through the programming excercices for the first Python classes all over again. But 30 minutes into this video I'm already seeing that pieces of information on objects and classes are starting to organize in my brains and everything is starting to make sense. This video fills nicely all the gaps I have in my understanding and also clears out all the misconceptions that I've had. Excellent work!
Thank you so much. This has been very clear and comprehensible. Your tutorials are always of such high quality, and it's incredible that you decide to post them for everyone to see. Please keep up the great work!
Really thank you for this very clean explanation. I´ve just started with OOP on my class and this helped me a lot to understand it. Thank you for helping with your videos, you encourage me to keep programming and learn new stuff.
That "Class Deep Dive" section was really helpful. I don't know why I've not seen that explained yet. You're helping to actually connect so much more under the hood than I've really seen yet. I will review that part again and again to make sure it's driven in.
Thank you for ClearCode explained classes. Man , you have the pedagogical gift !!! Thank you for your generosity for sharing your methods with the rest of the world. Be Blessed and Salutations from France.
This was amazing! Extra clear and mind-blowing. Thank you for your time and dedication
Such an underrated video.
Rooting for you, I'm sure this will get viral som day.
This helped me a lot with making my own games, well done!. Nice clarity and simplicity for really helpful teachings!.
Thank you, I asked for this video. Thank you for doing it! I would love a follow up on SOLID principles and design patterns.
Keep the good content up, mate! we all appreciate it. Even after a while of programming, I always learn something new from your videos. Thanks!
Literally getting setting up coding environment to continue learning basics , "notification pops up" just what i needed!
Many tutorial did not explain the self part as clearly as you, now I finally understands thanks!
thank so much, I can't stress how helpful this video was, you managed to explain te concepts behind the OOP and not just show how to write a code. so again thanks a lot.
Thanks for the video, really helpful, finally someone that explains OOP with real use, I was always clueless how to work with classes, every video just explains the same over and over with out showing real examples, thanks x1000
Came here to learn about OOP because CS50 didn't really do it for me at first. Cleared everything, and unlocked OOP completely. Thank you so much.
Nice clarity and simplicity for really helpful teachings!
Run into your channel a few days ago to learn pygame. I thought i should learn more about classes and boom - your video is out. You are awesome)
This is an amazing tutorial man. The best one I found in internet. Thanks a lot!
Having coded and using classes for many years. And having made video's myself (welcome to watch them). I can say that this video is a very clear and good explanation !!
Discovered your TH-cam channel yesterday through a video on Python's OOP concepts. Found it incredibly informative and easy to understand. Thank you for your commendable work! Just noticed there haven't been any uploads for months. Really appreciate your efforts though! 😊😊
This tutorial was extremely helpful! I tackled the Zelda python tutorial before this one, and I wish I had done this first. I understand so much more about classes and inheritance thanks to this video.
Beautifully explained! Thank you.
This must be the BEST tutorial about OOP in the whole Internet!!! It took me quite an effort to understand OOP conceps. But you make it so understandable and easy! 🎉 What about a series of videos about OOP patterns 8n the same style?
I'm only about 45 mins in and so far this has been way more understandable than anything else I've worked with yet in a college course. Thank you thank you. I will keep reviewing and listening because I'm determined to understand this subject more.
Keep making videos.
Your work is top!
Thank you for this amazing teaching, this lecture is very simple and clear.
This helped me a lot with making my own games, well done!
thank you for taking the time to make this video
Awesome tutorial, finish watching this in 2 days :)
It’s crazy to me that this youtube course is far better than the udemy course that i paid for, thank you man, i really appreciated ❤
Clear and understandable
I appreciate your efforts :)
loved the video thanks for the clear explanations
Good graces, this is some quality training!
another one man gotta love your style!
Amazing teacher. Thank you so much for helping me understand.
So Great , usefull and clear. All you need.
Thank you! It's really helpful!
Thank you bro for amazing video and knowledge. Superb !!
Just brilliant!!! Thank you man!
The best Python OOP explanation ever!
OMG, the video just i need today
great tutorial, thank you for sharing.
Really Really good and easy understandable video. Thank you
thank you so much for clearly understand how it works❤
Amazing tutorial.
A tutorial from the best!
Thank you very much for this helpful video...🎉❤
Beautiful. Thank you!
This is some TOP quality education!
Thank you Just the Video I needed
you are awesome keep it up💪
you always just come in time when I dropped the hole of "errr but!" great content buddy
Amazing. Thanks a lot!
very well explained!!!!!!!
Really helpfull. Thank You!
really well explained
THIS WAS GREAT!!
As a gaming fan this tutorial hit everything right on point for me!
You have a clear voice and the way you explain things is well thought out. Thank you
This video made me understand OOP, Thank You!
Generally, I do not comment too much bur just wanna say it is the best explaination
Thank you so much for this amazing video. Your explanation is amazing, the pacing is perfect and your voice is very soothing. The small jokes u make (like cant spell monster correctly) are funny, i end up laughing and learning something.
OOP always made me a bit uneasy but Im feeling way more confident now :)
Keep up the amazing work.
you are the best teacher......
best tutorial
Thanks!
Thank you!!!
Thank you, these things you just explained perhaps introduction to programming. However always looked down by other instructors or explained very quickly so you have to literally memorize not to learn..
I really appreciate your tutorials. I watch them and code along in the daily 1 hour train drive to my job. Keep up the good work and I will definitly continue to support you!
thank you so much! :)
@@ClearCode работай над акцентом чувак, тебя невозможно слушать
Thanks you. Now I understand..
Maybe the best Python tutorial I've seen - thanks so much!!!!!
Fantastic
This class was amazing! Very good.
Thank you very much! This is the only tutorial which finally helped me to figure out how OOP works! Awesome🤩
I had been trying to understand this topic for a while now. All I needed was a good teacher. Thanks!
Thank you so much and glad it helped! :)
thank you
Thank you very much! This tutorial helps me understand concepts like an inheritance that I was struggling with. I would like to know if there is any webpage where one can practice this level of exercises if anyone knows, thanks in advance!👍
1:21:00 when overwriting the move method i get this error:
Signature of method 'shark.move()' does not match signature of the base method in class 'monster'
i do exactly as in the tutorial, help
it doesnt gives an error when i put the speed parameter after self, but he doesnt do that in the tutorial
Nice 👍
what is great explaination bro subscribed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!😍😍😍😍😍😍😍😍😍😍
Isn't the self parameter pointing to object itself ? Why it's pointing to the class
I meant object, sorry
so as long as we are using **kwargs we dont need to know mro becouse the order doesnt matter? And we can alternatively use *args insted but then we would have to know mro and pass arguments in the exact same order?
I really like the theme you are using, can you tell which one it is?
agora sim vai entrar OOP na cabeça, obrigado pelo tutorial!
Thank you so much for your clear explanations! Would you think it's ok to name a foe with camelcase without uppercase at the beginning? Like eliteTroll for instance? i really like camelcase style and wish to use it more on other assets without confuse python with classes
The naming is entirely a convention thing, you can name a class anything as long as it is valid (so no spaces between names or dollar signs). Just be ready to be judged by other programmers when they see your code :)
What font you use in your slides?
Can we create multiple init method at time?
what text editor you are using?
Thanks so much for great explanations and clear code so to speak ;) I do have a ? in regards to one thing so far and I am about half way through the video but I am a person that gets hung up on things and can't move on until I understand maybe you can give a explanation
when using the __dunder__ method __len__(self): why can you only return one thing or is there a way and or need to return multiple things meaning in this video we see a example
def __len__(self):
return self.health
but you can not do
def __len__(self):
return self.health, self.energy
or
def __len__(self):
return self.health
return self.energy
hey, that would work. The single thing that is returned can be a list as well, or even a dictionary or a whole other class. And super happy to hear that the video is helpful :)
why why why I did not see this tutorials 7 months ago , I really want to re-learn python
I think this tutorial is well made, but I have to disagree on the graph and the need for classes argument at 15:00.
What are classes? - They are state self-managing data instances.
That means you should use classes when you need that and not else.
It's common to see programs that do cohesion by class and not by file.
So you end up having classes containing methods that surely could live without the additional namespace of the class.
If you really wanted to you could use a package on top of the file if you want to additionally define an interface on top of the functions.
On the other hand, if you are only concerned with data then use ... well the data.
No need to shoehorn it into a class if the data could live without it.
Yeah, your IDE will text complete a data class but not a dictionary key, but that's not an argument in my mind at least.
So it's possible to have a project with thousands of lines, or more realistic; some packages/modules of a bigger program, which do not contain classes at all.
A use case in which I think classes are the wrong approach is data transformation for example.
About complex inheritance, isn't it way more easier to initialize every parent class sperately? It is the same amount of code and way more easy i think but I'm new around here so I may be wrong. For example:
class Monster:
def __init__(self, health, energy):
self.energy = energy
self.health = health
def attack(self):
print("Isırdım")
class Fish:
def __init__(self, speed, has_scales):
self.speed = speed
self.has_scale = has_scales
def swim(self):
print(f"yüzüyorum şu hızda {self.speed}")
class Shark(Monster, Fish):
def __init__(self, bites, heath, energy, speed, has_scales):
self.bites = bites
Monster.__init__(self, health, energy)
Fish.__init__(self, speed, has_scales)
def deneme(self):
print("oldu mu")
but why cant you just use the for loop with monster.attr = value?
Wordle would be a fun tutorial! Or maybe minesweeper?
