What are Iterators in Python?

Iterators in Python is an object that can be used to contain any value that can be counted. Using the iterator the values can also be iterated and can be traversed, all the values inside the iterated can be traversed through. If it is looked upon technically, in Python, the iterator is an object that can implement the iterator protocol, the iterator object contains the method _iter_() and _next_(). The strings in Python are also iterable objects, but iterator and iterable are different objects.
