When should I use iterators instead of lists?

When should I use iterators instead of lists?

You should use iterators when you want to traverse a collection without exposing its underlying structure, especially for large datasets.

Can you give me an example of when iterators are more efficient?

Sure! Iterators are more efficient when dealing with large data streams, as they allow you to process items one at a time without loading everything into memory.

What are the advantages of using lists over iterators?

Lists are easier to use for random access and allow for more straightforward manipulation of elements, like sorting and slicing.

Are there any downsides to using iterators?

Yes, iterators can be less intuitive and may require more code to implement compared to lists, especially for beginners.
