For factories I prefer to use a dictionary with the key strings and the value being the class in the build_person to avoid the cost of comparison as follows
def build_person(person_type):
PERSONTYPES = {"Student":Student, "Teacher":Teacher}
return PERSONTYPES[person_type]().

That is probably how you would do that in Java. But in Python we just use a function that returns the object.
You can already see that because you made it a staticmethod, and a class with just one function (and even worse a staticmethod), is a clear indicator that it should be a function, not a class.

I was trying to understand this topic since past one week and watching multiple videos was making me more and more confused. I understand it through this video. Thank you for explaining so well in this video.

These pattern tutorials are gud, please we need more and eventually creating a project with one

[manifaridi]

You proved programmers can also have biceps 💪

[kevinjones]

The clarity of your explanation/example of the factory pattern is awesome!!!

[bhaveshvaishnav]

Explained with such a simple way without complicating anything. Awesome!!

Hey man, I know you don't have a lot of views yet, but when programming becomes a core subject in schools, you'll be the khan academy of the future. Keep on the grind G

Thanks for all the valuable videos, supported you by buying all the seven books. :)

[pythonisthebest]

You’re unbelievably cool! Keep up the good work!

[ddjambel]

You need always self in a object, because self, it the object itself, to use all attributes or methods, over "self.".

can anyone tell me difference between Factory Design and Abstract Factory Design ?

[deeprony]

Having the if-else logic still reside in the ConcreteFactory violates the Open-Closed Principle. Would it be better to have an interface for FactoryPerson and implement Student and Teacher from it?
If so, how would that implementation look like?

Which text editor are you using bro???

[hasibislam]

I'm really liking this advanced python you please make a video describing what meta classes and how they work?

[golammuhaimeen]

that was a really nice and simple example man. thank you so much. cleared up my understanding of a factory design pattern

[heroicrhythms]

instead of hardcoding "student" and "Teacher" values, you can use an ENUM

[jerielmorales]

Great Tutorial. Part 2 of Vim course next =)

[jrgomez]

Great explanation as usual. I'm defintively a rookie on OOP, but I'm learning a lot. Thanks !

[gauffr]

helpfull, thanks, I'd rethink the use of conditions in factory
