In Python, we have three types of constructor default, Non-parametrized, and parameterized constructor . Using self, we can access the instance variable and instance method of the object. The first argument self refers to the current object. Constructor overloading is not possible in Python.28 Ağu 2021
Read moreWhat is constructor in Python?
A constructor is a special kind of method that Python calls when it instantiates an object using the definitions found in your class . Python relies on the constructor to perform tasks such as initializing (assigning values to) any instance variables that the object will need when it starts.16 Eki 2019

Python has a module called abc (abstract base class ) that offers the necessary tools for crafting an abstract base class. First and foremost, you should understand the ABCMeta metaclass provided by the abstract base class. The rule is every abstract class must use ABCMeta metaclass.29 Ağu 2020
Read moreWhy do we need ABC in Python?
ABCs provide a formal way to define interfaces in Python, while staying true to the spirit of duck-typing . Besides, this works in a way that honours the Open-Closed Principle.
Read moreWhat does ABC Abstractmethod do?
abc. abstractmethod(function) A decorator indicating abstract methods . Using this decorator requires that the class’s metaclass is ABCMeta or is derived from it. A class that has a metaclass derived from ABCMeta cannot be instantiated unless all of its abstract methods and properties are overridden.
Read moreShould I use abstract classes in Python?
When we want to provide a common interface for different implementations of a component , we use an abstract class. Why use Abstract Base Classes : By defining an abstract base class, you can define a common Application Program Interface(API) for a set of subclasses.
Read moreWhat is Python interface called?
python informal interface is also a class that defines methods that can be overridden but without force enforcement. An informal interface also called Protocols or Duck Typing . The duck typing is actually we execute a method on the object as we expected an object to have, instead of checking the type of an object.
