Thanks, the most useful series that I watched, don't stop creating these videos

I don't know who isn't convinced that's Microservices isn't the way to go

Amazing guy! Good explantion! Me, as well, was watching a lot of videos and yours was the best and simple to understand. I already have applay this in a project here. Thanks!

Best Channel for learning patterns with Java. Thank You!

I think your method "create" should be "Create". Like your method "Pay", or like Console.Writeline.

Oh wow, that was amazing videoooo!!!! Thanks a million :)

Very insightful! Thanks Seca

what app do you use for these diagrams?

is it recommended when we add more number of language & CIty?

Thanks for this! Such a rare skill to be able to explain CS concepts this concisely.

Excellent tutorial .

Very informative. <3

The best tutorial I have seen so far. cheers mate

You've missed a client isolation implemanaton which would isolate from growing list of your Branch classes. You should have something like Branches class which would compound of all branches, Basically O/C Principle.

Excellent explanation thank you so much

Wonderful lesson❤ Simple, and yet covered all important aspects.

your explanation is very helpful , but I think there is still chances of being the OCP violation. because, in the future we can add ApplePay, VisaCardPay, MastercardPay etc type of payment methods. then we will have to rewrite our enum (basically we will have to add new options in the PaymentMethod enum) and we will have to add more options in the "switch case" PaymentFactory.create method. in this case we can use the help of reflection. so, we won't have to add any more new options to any enum or swith case. Please correct me if I am wrong. I will be delighted to know my mistakes. Thanks a lot for you video. I hope and pray for your wellbeing.

This only video resumed more than 6 hours in-person classes and three times more hours of study. At almost 50 my head is not that fast to understand these concepts, so thank you very much for this priceless piece!

Amazing

thank you!

Great video! The music and your commentary are very relaxing. You might be interested in my library, M31.FluentAPI, for generating builders via Roslyn source code generation. Keep up the great work!

I've read that a global variable in python, natively behaves like a singleton, for instance like all the modules once imported, they don't make a difference when trying to re-import. Could you also touch base on that approach and hopefully explain us viewers pls. thanks in advance.

Good one, also can you extend this to make it a thread safe one ? pls.

Great video! I was watching one of your other videos explaining abstract factory methods in C#, but halfway through it was marked as private, so I didn't get to see the rest. Will it come back up?

A good straight forward example that gets the principle across, thanks for posting.

A perfect example of the meaningful application of the Factory Design Pattern. I have seen dozens of videos. This is the only one that clearly shows the benefits of the Factory Pattern.

Please add more designs pattern in python and some advanced concepts of python . Your lectures are very good 😊

Low key one of the best explanations I’ve seen of this without BS and annoying editing.

Best tutorial I have seen on this subject. The example classes were much easier to follow and therefor understand without 'abstract' examples such as foo / bar - thank you!

Why not this.Teacher.MemberwiseClone() as Teacher in 17:52? I liked the video

what if you have huge data like 100000000comments in Post object. I don't think you can init a domain object with that much... looks useless to me when dealing with large chunks of data. Thoughts?

Thanks, great tutorial!!!

I think we need to return the individual factories from the provider methods, and not the interfaces.

Not that it matters too much, since Python is a dynamically typed language. I'm not even sure if a tool like mypy would even catch this. But in 4:15 you want to specify the actual "type" of the method's return type, and not an instance of the expected type: @abstractmethod def list_top_attraction(self) -> list[str]: ...

can you add all the design pattern for python.

Hello sir, would like to ask a question regarding the code in the GitHub repository. In the product class (email_message.py) I see that youve placed a setter method for 'to', which is def set_to. But in the video and the repository, the builder class makes use of the get_to method to get the argument passed to provide the value for 'to'. I may have overlooked it on my part, but I dont see the set_to method being used and I'm kind of confused regarding its purpose. I'd just kindly like to know where the set_to method is being used. Thank you very much!

would be great if the example shows use case for multiple interfaces in a builder pattern..

So easy to grasp .

Really helpful !

So simple . Thanks a lot !

Thanks for this video, it's very helpful! One question, however. Using the example at 19:00, what is the correct way to accept a parameter on line 7? We may need to accept "South" or "North" as parameters of SpainFactory constructor to make sure language changes from "Spanish" or "Catalan" respectively. Is there a better pattern for this or do we simply make custom constructors in SpainFactory?

greatly helpful video thanks!

Clearly, perfectly explained

What extension is he using to get that dropdown menu for creating new C# documents quickly?

UNDERSTOOD EVERYTHING. THANKS MAN!!

Hi I’m learning design patterns I like your videos but can you possibly make a video of when I should maybe use factory method vs abstract. I understand there isn’t a simple answer but maybe a “Look for these signs answer”

Great video. What font are you using on vsCode?

your video so top. respect from Ukraine. keep making videos.
