1. no, double-underscore does not mean 'private'. There is no concept of 'private' in Python. You should have used _name, age, gender.
What you did was name-mangling, which only means it is slightly harder to access the variables.
2. Do not use Capitals for methodnames (pep-8). No idea where you picked up that its a 'convention', but it isn't. Only capital for Class names (not objects).
3. You are using @staticmethod incorrectly. It should be outside of the class, because it is already in the module, so no issue with collisions. What you probably want is a @classmethod. There is no real use case for @staticmethod and according to Guido "it was somewhat of a mistake".

Great way of explaining Encapsulation in Python. I would add though that real Encapsulation is not a thing in python, since you have access to __private variables through object's __dict__ / class's __dict__, unlike other languages where private is really private. This seems to me an important feature that people should know about. Maybe a subject for another video 🤗 ?!?

I would have to say that using self.__param = param in the __init__ method is not the best option if you need to validate the param. The flaw is that when first instantiating the class, the param doesn't go through validation. I would say it's better to use self.param = param, and then the setters and getters will return self._param. When the __init__ method runs self.param = param, it will run the internal setter thus using the validation when instantiating the obj.

Always breaking the league bro ..good job!

Nice video, I really enjoy your videos and there are simple to understand!
By the way what's your opinion for encapsulation in python?
Since it really feels like there isn't a language capable of doing something like that efficiently.
For an example you can easily bypass the setter method and store "Bob" as name with ```p1._Person__name = "Bob"```.
Anyway keep up the good work!!!
Edit: Forgot to request for a video about threading/multiprocessing!
Do you have plans for it in the near future?

This is a great advanced series. Very helpful.

[hovardlee]

In case of example, even if you do not have @property then you can still use p1.Name() instead p1.Name

[bjorncalbes]

so should you always use getter and setters where you can on yout code?

What terminal are you using?

Nice nvim setup btw

[zombiekiller]

Nice!!!
Please suggest best language to create gui apps, tkinter is way too slow

[MananGandhi]

Hey! Which IDE are you using in the video?

[cybersecurity]

Can you explain vim editor and how to use it

[rafaeel]

Does the same apply to protected attributes?

[amitshogun]

I believe it is possible to set the __ attribute by using their mangled name. Thank you

[gotitboom]

you just called Bob basic ahh bih lmao

[guga]

Can you make video about creating WAF with python?
