def __enter__(self) and def __exit__(self) are really useful too. It allows you to use the with() keyword with your class. __enter__ defines what happens as soon as the line with the "with" keyword runs. You don't need to do anything special here, just make sure you "return self" __exit___ defines what happens as soon as the scope changes or there's no more code left to run. Just clean up and/or close files, active connections.etc

It's called context manager, like open function

What font are you using? The characters combining into one arrow seems interesting

@Nicfallenangel 5 ай бұрын

I'm not sure exactly what font he is using, but it's probably a Nerd Font with "font ligatures" turned on. Ligatures is the feature that combines the characters. I use a font called FiraCode that has support for ligatures and it looks weird now any time I'm using some other system that doesn't support them.

If I have an application made in Python and a copy is given to a person in America and a copy is given to a person in Italy, how can I make the two people exchange messages with each other? Can you give information about this?

@Indently 5 ай бұрын

If you're talking about creating a chat app, you need to look into writing code that runs a server that both of you can connect to. One of you will have to run the server, but then anyone can connect to it.

Has this been explained previously on your channel?

@celestialowl8865 5 ай бұрын

Maybe consider coveirng infix operators. Not super useful at least as far as clean code goes, but certainly a neat trick

Thanks for the suggestion, looks super interesting as a trick ahaha, probably will be one of the next shorts

Can we create user magic method?

@Y0annSA 5 ай бұрын

You technically can define a method named __banana__ (for example), Python doesn't forbid it, but it wouldn't be "magic". Standard dunder methods are methods that Python automatically calls under specific situations. Since Python wasn't programmed to use __banana__ in any way, it wouldn't have any effect unless you call it explicitly. It's just a normal method with bad naming convention. You would have to fork and develop your own version of Python to create a new magic method

@Indently 5 ай бұрын

I think we should start a petition though to make __banana__ a world standard by Python 3.15

@@Indently I just found out that writing dunder methods in youtube comments is really annoying since it really wants to make them italic (and removing a pair of underscores in the process). But I found a little cheat by writing a zero-width space immediately after (still not very convenient to find and copy one) (or you could add an extra pair of underscores and accept that it's italic)

@Indently 5 ай бұрын

But I really like the single underscore Italic version, because as Python devs we all know what we were trying to do xD
