How does __init__ work?from askpython.com
The __init__ () method takes self along with the two state variables as input. Then we initialise the object by setting the state variables of the object to the user-defined value.
What is the parent class constructor called in Python?from geeksforgeeks.org
A init called B init called. So, the parent class constructor is called first. But in Python, it is not compulsory that parent class constructor will always be called first. The order in which the __init__ method is called for a parent or a child class can be modified.
What is the self keyword in Python?from askpython.com
The ‘self’ is a reserved keyword in python which represents the instance of the class. The ‘self’ keyword allows easy access to the class methods and parameters for use in other methods of the class.
What is the purpose of a constructor?from geeksforgeeks.org
Constructors are used to initialize the object’s state. The task of constructors is to initialize (assign values) to the data members of the class when an object of class is created. Like methods, a constructor also contains collection of statements (i.e. instructions) that are executed at time of Object creation.

What is the purpose of __init__ method?from geeksforgeeks.org
The __init__ method is similar to constructors in C++ and Java. Constructors are used to initialize the object’s state. The task of constructors is to initialize (assign values) to the data members of the class when an object of class is created. Like methods, a constructor also contains collection of statements (i.e. instructions) that are executed at time of Object creation. It is run as soon as an object of a class is instantiated. The method is useful to do any initialization you want to do with your object.

If you take a closer look, you will realise that we have used the methods, self.length to derive the value of the attribute length. The attribute length is already bind within the class, and we are using the self method to represent the object within the same class.
What is __init__ in Python?from askpython.com

def __init__ (self, n): won't be checked but def __init__ (self, n) -> None: will. Even though we know that __init__ should only return None, a checker is not supposed to special-case it. The reason is that you don't know if the author intended to have def __init__ (self): checked or not.
What does def __init__ mean in Python?
def __init__ (self, n) -> None: means that __init__ should always return NoneType and it can be quite helpful if you accidentally return something different from None especially if you use mypy or other similar things. But you can ignore it if you prefer the old way to do it.
Why does mypy ignore unannotated functions?
The main reason is to allow static type checking. By default, mypy will ignore unannotated functions and methods.

A brief illustrative example
In the hope it might help a little, here's a simple example I used to understand the difference between a variable declared inside a class, and a variable declared inside an __init__ function:
Class objects support two kinds of operations: attribute references and instantiation
Attribute references use the standard syntax used for all attribute references in Python: obj.name. Valid attribute names are all the names that were in the class’s namespace when the class object was created. So, if the class definition looked like this:
Here is my example
class Bill (): def __init__ (self,apples,figs,dates): self.apples = apples self.figs = figs self.dates = dates self.bill = apples + figs + dates print ("Buy",self.apples,"apples", self.figs,"figs and",self.dates,"dates. Total fruitty bill is",self.bill," pieces of fruit :)")
