A debugger is a program that can help you find out what is going on in a computer program. You can stop the execution at any prescribed line number, print out variables, continue execution, stop again, execute statements one by one, and repeat such actions until you have tracked down abnormal behavior and found bugs.
What is self function in Python?
The self keyword is used to represent an instance (object) of the given class. In this case, the two Cat objects cat1 and cat2 have their own name and age attributes. If there was no self argument, the same class couldn’t hold the information for both these objects.
How do you use a static method in Python?
To declare a static method, use this idiom: class C: @staticmethod def f(arg1, arg2, …): … The @staticmethod form is a function decorator – see the description of function definitions in Function definitions for details. It can be called either on the class (such as C.f() ) or on an instance (such as C().
How do Python classes work?
Class creates a user-defined data structure, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class. A class is like a blueprint for an object. Some points on Python class: Classes are created by keyword class.
What are Python classes used for?
Classes provide a means of bundling data and functionality together. Creating a new class creates a new type of object, allowing new instances of that type to be made. Each class instance can have attributes attached to it for maintaining its state.

- # iterating till num to append elements in list.
- for i in range(1, num + 1):

How do you make a set in Python?

What is a Python class?
A Python class is like an outline for creating a new object. An object is anything that you wish to manipulate or change while working through the code. Every time a class object is instantiated, which is when we declare a variable, a new object is initiated from scratch.
What is class method?
A class method is a method that is bound to a class rather than its object. It doesn’t require creation of a class instance, much like staticmethod. The difference between a static method and a class method is: Static method knows nothing about the class and just deals with the parameters.
What is a Python decorator?
A decorator is a design pattern in Python that allows a user to add new functionality to an existing object without modifying its structure. Decorators are usually called before the definition of a function you want to decorate.

An object is simply a collection of data (variables) and methods (functions) that act on those data. Similarly, a class is a blueprint for that object. We can think of a class as a sketch (prototype) of a house. It contains all the details about the floors, doors, windows, etc.
What is self Python?
The self is used to represent the instance of the class. With this keyword, you can access the attributes and methods of the class in python. It binds the attributes with the given arguments. The reason why we use self is that Python does not use the ‘@’ syntax to refer to instance attributes.
