__call__ in Python

In this video, we will discuss the _call_ method and how to implement it in a class in Python.
When we invoke a function, we simply use the function name with parentheses(func()). This notifies the interpreter that a function is being called. Internally, it is equivalent to this expression func.__call__(), because functions in Python are objects and the call method is what gets executed when the function is invoked.
So, when we call a function in Python, the interpreter executes the _call_ method of the function object behind the scenes.

Never seen this before. First half of the video I was like 'ok, another dunder method, so what', then the example with the API makes all the sense in the world... Thanks!

[@2MinutesPy]

Nice 👍

[@LootBoxLegendsYT]

@@2MinutesPythen why should not that call to api go to constructor or a diff method?

[@spidey2468]

Never ever a day goes when I feel how underrated this channel is , Pls start a series on something around this ❤

[@2MinutesPy]

Thanks, sure

[@youngsci]

I have been looking for a Python daily refresher, and thankfully, I found your channel. Thank you for the high-quality, short, and informative videos.

[@2MinutesPy]

Glad it was helpful!

[@10uRization]

The most underrated Python channel

[@2MinutesPy]

Thanks for the support

[@dweepverma3662]

I really want this video to go viral, it's just great 👍. Thank you 2minutespy

[@2MinutesPy]

Thank you bro

[@maxpythoneer]

Nice one😊❤

[@2MinutesPy]

Thanks

[@pedrohfahrenheit7347]

It's a great channel. I routinely struggle when I'm studying programming, because I can't grasp the content well when I don't get the background of it. Knowing how a bit of it works is, as someone in the comments already said, refreshing! There is some specific name for those aspects and processes that happen behind the scenes in Python? I would like to search it more profoundly by myself (Sorry for any English misspelling, learning yet)

[@hackytech7494]

Thank you so much for this video 🙏❤

[@2MinutesPy]

Most welcome 😊

[@krzysiekkrzysiek9059]

Finally bro. Thx 👌

[@2MinutesPy]

Much welcome

Nice one! Short clear and useful learning video = Subscribed! Just to confirm my understanding- you could have made a function inside the class (eg callAPI) and call it like this: response = client.callAPI("users", id=123), but this dunder call is the easy to use/shortcut version of the same, by having a default function (__call__) be called directly? No other real change I presume?

[@2MinutesPy]

Yes, you are right

[@ombiradar1969]

So the dunder call can be used as a constructor for a class too?

[@2MinutesPy]

No, this ain't true. The dunder call can be used to make instances of the class callable like function. for example: `hello = Hello()` - Now wen can make `hello` instance callable like this `hello()` and pass arguments if the dunder call is defined within the `Hello` class.

bro got caught to the web 💀

[@2MinutesPy]

ha, really!
