Python's "self" is really just a variable that points to the current instance of our class. Every method you define must accept "self" as its first argument.

Add "Python ASMR" to the video title

Wow! And I was about to comment about how this guy's voice has a perfect tone for ASMR, lol!

I like the short content. I also like “this” better because I am already used to that from C++ 😂

@vorfreu 6 месяцев назад

too silent, you can make the video a bit louder

@ichoudhury007 5 месяцев назад

I think sometime soft soothing voice can be more effective at honing the lesson better than being loud and rambunctious :)

This is why I prefer ruby. Self is the instance, no need to pass it around.

@PythonMorsels 2 месяца назад

As a method caller, we don't actually need to pass it around because Python does the "passing" part for us. But as a method definer, we do need to accept it as an argument which will be passed in. That's not to say Python's style is better though...it definitely takes some adjusting to get used to that passed-in self!

Still, it makes the syntax look gross..... self everwyere as a hidden 1st variable to function...

@akashbharadwaj1 3 месяца назад

awesome explanation man... really great.. so can we have different words for each instance? like can we have self in one method..... this in other method... or xyz in another method..... can we have different ones in each? i am not asking about best coding pracitces.. i am asking CAN we do it? can it be done?

@PythonMorsels 3 месяца назад

Absolutely! 👍 You CAN though of course you shoudn't. Here's an example: pym.dev/p/2cn9c/

@yoavmor9002 5 месяцев назад

Yet another Python quirk that becomes IMMEDIATELY simpler when you write a bit of C. There is no such thing as a function that can magically access some local variable. For the function to have access to the data of the object, the object must be passed into the function. That is self.

i want to add that your comment made the video meaningful to be very honest. i read your comment and watched again.. and everything was so clear .. thank you sooo sooo much. really. god bless you thanks

@yoavmor9002 3 месяца назад

@@akashbharadwaj1 Yeah it's possible, all it is is a name for a parameter. You can call it self in the __init__ function, call it stringable in the __repr__ function and call it this_object in a func function

Don't encourage him! His current mic set up gives his voice a perfect ASMR quality. This video helps treat insomnia, lol!👍

Ironically, his voice has that perfect ASMR pitch that, while apparently not getting enough nightly rest, he can easily talk others into getting the kind of profoundly deep sleep that he himself needs!
