What are the differences between iterables and iterators?

What are the differences between iterables and iterators?

Iterables are objects that can be looped over, like lists and tuples, while iterators are objects that keep track of their current position in the iteration.

Can you give me an example of each?

Sure! A list is an iterable, and you can create an iterator from it using the iter() function. The iterator can then be used to access elements one at a time.

How do I convert an iterable to an iterator?

You can convert an iterable to an iterator by using the iter() function. For example, my_iterator = iter(my_list).

What happens if I try to iterate over an iterator again?

If you try to iterate over an iterator again after it has been exhausted, it will not return any values. You need to create a new iterator from the iterable.
