The Internals of Operations Like len() and []. 6. This method helps to replicate the multiple constructor feature in python. This is probably a really stupid question, but I cant seem to find a satisfying answer by myself so here it goes. when an instance of a class is created, python calls __init__() to initialize the attribute of the object.
