Magic Methods & Dunder - Advanced Python Tutorial #1

thank you for making nice content! appreciate your work!

I was just here to listen 👂 to those soothing and accurate key strokes

Look at me! I use neovim! … on… ::squints:: windows 10

Thanks for this great content!

Nice!

Amazing explanation!! Thank you

Who feels proud to finally come to learning advance python from the beginner version?

👇

Thanks

Great video.The Vector class example is not a vector, is a point in a 2D space:)

thank you for your nice video
your video have good quality and people can learn thing form those .

thanks man

Thanks dude, that's exactly what I need

started from the beginner series to here thank you for making these videos!

There's two mistakes worth mentioning here. When discussing _len__() you suggested that the correct way to do it for your Vector example would be Math.sqrt() to get the magnitude of the vector. __len_ is not just any arbitrary "length" it's supposed to be used to identify the items in a collection. It needs to return an int, not a float and you shouldn't be implementing dunder methods for some alternative use, it needs to keep the intended meaning. The other mistake was in _repr__(). There's __repr_ and _str_ and the reason why there's two of them for a very similar thing is because _repr_ isn't just some arbitrary string, it's supposed to be valid Python. As an example, the following should be true for a class where the _repr_ and _eq_ methods are properly implemented: "obj == eval(repr(obj))"

It's more or less serializing the object. You could have _str_ implemented exactly as you demonstrated, if _str_ is missing then converting to a string will fall back to using __repr__.

That is really cool! Great video thank you! Can't wait to try these in my coding. Looking forward to watching the rest of the video series

in java, i don;t need to do obj.toString(), once defined, i can simply print it out as well

Thank you so much. I will have an exam that covers this soon and this helped me understand very well.

Dropped a like just for using Nvim. Automatically more trustworthy.

You look the spit of a dude my son used to watch play Fortnite

Thank you very much for the perfect lesson! Despite being very hard, I successfully persistent and have mastered perfectly!

Thank you.

Can you tell me what IDE you use

Loving the series. Keep it up

which background music did you use?

i tried to learn python a bunch of times wish i started with the advanced stuff because beyond basic print input and out put stuff the rest just seems like static until this video!

well i like VS Code because it allows me to change zoom level, including the UI itself not just the text, then you can customize highlight and any other colors, you can also multi tab splitting the editor in multiple pages instead of running multiple IDE's and split them on screen, you can also do a lot of stuff with shortcuts, move between open files with CTRL+TAB, go to console and back to code with CTRL+ ` , open /close file explorer CTRL+B, it has support for basically any type of file extension (and if it doesn't it will popup the option to install a plugin for it)
have multiple terminals, and customize so much more with extensions
the best thing about it is that you can debug and have the code and the console in the same window

Thanks for sharing!

_repr_ method is for programmers, so should be return "Vector(60,80)".

Intro beat hitting harder than my dad's belt. T_T

I don't think this is advanced python, more like intermediate level. _repr_ in particular
But great video nonetheless

So _call_ only works in the bash console? I couldn't get it to show anything in IDLE

Thanks for the lesson

Nice video

can i get a video on how to make any custom class object completely immutable, i would love that indeed.

great, as Java developer we need to learn quickly python to be operational

If don't know but I think this letters are too small

buffed Tech with tim

Love the python video!

Very thanks for all your efforts and informative courses. I am learning a lot from your great contents.

nice :D

the content is very informational. what IDE and theme are you using?.

You made my day! That was the best simplest way to train these Dunders

Subscribed! Thanks!

I loved it not only liked it

from last series you evolved from software engineer to navy technician xdxd

Shit, this was so advanced

You have a link for you vim dotfiles? Clean looking setup

What is your ide
It is vim new vim?
