Title: Understanding Python For Loops and Iterators - A Step-by-Step Tutorial
Introduction:
Python's for loop is a powerful construct used for iterating over sequences, such as lists, tuples, strings, or any other iterable object. In this tutorial, we will explore the basics of the for loop, how it works with iterators, and provide practical examples to help you grasp the concept.
An iterator is an object that allows you to iterate over a sequence of elements one at a time. In Python, an iterator implements two methods: __iter__() and __next__(). The __iter__() method returns the iterator object itself, and the __next__() method returns the next element in the sequence.
