What's the meaning of underscores (_ & __) in Python variable names?

Thank you, the video covered everything I needed in a very convenient amount of time

Super informative, thks.

self.__mifflin='paper company'

So for the encapsulation, should we use single underscore or double? Thanks.

Someone tells me how to type this long underscore

How do you get those sweet suggestions in your shell's python interpreter?

python is a cool language except its OOP concept

Dunder Mifflin .. hue hue

How are we able to access magic methods normally then? Are they not name mangled? That is,
"Hello".__len__()
"Hello"._str__len__()
The first one works fine despite being a private method. The second I never tried.

__attr == _Class__attr

Thanks for making this useful video

Good explanation, only suggestion is to use t._dict_ instead of dir(t) since it won't return many builtin methods.

Hi,Sir Dan.JV here again.Your video is really nice and I could understand everything,sir.I have view this video,like this video and subscribed the channel,sir.

Please correct me if wrong, but I was under the impression the _init_ is merely an initializer, where _new_ is the underlying constructor?

Hey bro please explain how to write double merged underscores

Hi, sir.. How to remove these underscore?

Thank you sir!

You did not show how to access the dunder bazz __baz within the class.

Do you use the class name, then dot notation to get to __baz?

Example:
Test.__baz
>>> 42

Is this how to get the 42?

single underscore usually means private variable, double (dunder) means new classes will use the name mangling correctly with variables with same name
dir() returns attributes

I would've loved to see what happens when you extend your Test class. Like would there be _Test__baz AND _extendedTest__baz or just the latter? I guess I'll have to go do it myself...

Now I want to call all my variables __mifflin.

-__-

What interpreter you use? It’s give some tips when you type function. I have never seen that before.

but what if I want a variable named _Test__baz?

Yay! Subbed.

Blimey. The more I see of python the more I see a horrible mess.

How do you have syntax highlighting and suggestions?

Cus it is _snake_

Anybody know what console / editor this is. It looks pretty cool

i still dont get it

OMG. Ugly hack after ugly hack. Probably learned it from C++. You can't you do the sensible thing an just make the thing private? Inaccessible. Out of the symbol table.

I wish I was this clear when explaining concepts

I have seen stringly typing, we all have, php and js used to use it, but this is probably the first time I've ever seen stringly scoping.

A third underscore will make Thunder

Plz Plz add arabic caption

This is such a nice video...clear concept, beautiful

Yikes. The more I look at Python, the more I wonder why anyone would use it? 🤔

.

I don't get it, gonna come back in a few weeks!

And anther reason I'll never use this garbage language.

No real access restrictions. Geat language!

Took you 1.min 32 seconds to begin explaining the differences.

So how would be the correct way to access __baz ?

What shell do you use?

python is so messy, in other languages like js you dont have to worry about this

wow new concept you explaining 😍

What IDE is this?

All the things about Python you never had the courage to ask about
