How do iterators work in Python?

Can you explain how iterators work in Python?

Sure! In Python, an iterator is an object that allows you to traverse through a collection, like a list or a tuple, without needing to know the underlying structure.

What is the difference between an iterator and an iterable?

An iterable is an object that can return an iterator, while an iterator is the object that actually performs the iteration. You can think of an iterable as a collection and an iterator as a tool to access the items in that collection.

Can you give me an example of creating an iterator?

Certainly! You can create an iterator using the iter() function on an iterable. For example: my_list = [1, 2, 3]; my_iter = iter(my_list).

How do I use the next() function with an iterator?

You can use the next() function to get the next item from the iterator. For example, next(my_iter) will return the first item, and subsequent calls will return the next items until the iterator is exhausted.
