Python Class Methods
Methods are functions that belong to a class. They define the behavior of objects created from the class.
What is @classmethod in python and why we need this , when to use it?
A "normal" method is tied to an object instantiated from the class. A class method is called from the class itself instead of an instance. The first argument of a class method is the class itself (usually called cls instead of self because of that). One use is e.g. mass instantiation. Let's say you have a list of whatever that you want to parse and turn into instances of your class. You could manually loop over the list and call the constructor a lot, or you could make a class method that does it for you and returns a lit of instances, so you can easily re-use end extend it in sub classes and such.

February 19, 2022A question about @classmethod
No. Why should there be?
Your problem it's that you're confusing yourself by calling the first argument to the class method self. That implies an instance, but the value is not an instance, it's a class, which is why the convention for a class method is to call the argument cls. That makes it much more obvious that the only things you can do with it are class things, like instantiating an instance, not instance things like setting instance values.

Python when to use a Classmethod or a staticmethod
I just read the whole blog post. Nearly everything in it is wrong.
The primer in Part 1 is much better than Part 2. There are a few confused or wrong parts in Part 1, but it's not terrible. However, Part 2 is basically nonsense.
