The word Polymorphism means the ability to take various forms. Map Function Python has an inbuilt function called map () which permits us to process all the elements present in an iterable without explicitly using a looping construct. __next__ will be called to get the next value. Also called Dunder (or double underscore) methods, magic methods are special types of functions that are invoked internally. Something similar also exists for __i(method)__ when the calculation would be done in place, such as a += 5. You can even return another class object! Advanced Lessons. each taking their own set of arguments and operating upon them. Some dunder methods are well known, like __init__ or __str__. This is useful if you have some default functionality to use in the class or when you want to use methods and objects interchangeably. They are series and Dataframe which is supported by pandas. 100 Days of Code with GFG - Get Committed to a Challenge! Python is the most popular programming language in the world.
