In the previous definition of both concepts; we define class attributes outside of all the methods, usually they are placed at the top, right below the class header. i.e.

What are the differences between class and instance attributes?

As we saw in the previous example, class and instance attributes are different. Class attributes are accessible to all instances of the class, where instance attributes are accessible only to that particular instance of the class. We can access a class attribute via an instance or the class name, whereas an instance attribute can only be accessed via the instance to which it belongs.

What are the advantages and drawbacks of class and instance Attributes?

How does Python deal with the object and class attributes using the __dict__

Python’s class attributes and object attributes are stored in separate dictionaries. which they use to store their attributes and their corresponding values, as we can see here:
