Python Iterators Iterators are objects to be iterated onto. You'll learn what iterators are in it during this python tutorial , and also how to apply a Python iterator. We'll also explore how iter and the next methods can be used to build our own Iterators. What are the iterators in Python? Iterators are all over Python. Iterators are artifacts in python that is widely used to iterate over a set of values, elegantly implemented within them for loops, understandings, generators, etc., but concealed in plain sight. It is only an entity iterated upon. An object capable of returning data, one item at a time. Technically speaking, the Python iterator object has to follow two special methods, iter () and next (), named the iterator protocol, collectively. 1. __iter__ method. This is called upon to create an iterator. It will return an object with a next step, or next. 2. Next method The next method by the iterator returns the following v...
