How do generators and iterators compare in performance?

Generators are generally more memory efficient than iterators because they yield items one at a time, while iterators may require storing all items in memory.

Can you give an example of when to use a generator over an iterator?

Sure! Use a generator when dealing with large datasets where you want to process items one at a time without loading everything into memory.

What are the performance implications of using one over the other?

Using generators can lead to lower memory usage and potentially faster execution for large datasets, while iterators might be faster for smaller, fixed-size collections.

Are there any scenarios where iterators are preferred?

Yes, iterators can be preferred when you need to access elements multiple times or require random access, as they can provide better performance in those cases.
