Factory Method is part of the Creational Patterns where these patterns provide various object creation mechanisms, which increase flexibility and reuse of existing code.

AsyncIO is a built-in library of Python to write concurrent code using async/await syntax. This library provides high-performance network and web servers, database connection libraries, distributed task queues, etc., for asynchronous programming.

A class in python is a list of data set allocation attributes and their values. A data class is a class typically containing mainly data, although there aren’t really any restrictions.

Python Functions are a block of statements that return a specific task. The idea is to put some commonly or repeatedly done tasks together and make a function so that instead of writing the same code again and again for different inputs, we can do the function calls to reuse code contained in it over and over again.

Iterators are methods that iterate collections like lists, tuples, etc. Using an iterator method, we can loop through an object and return its elements.
