What are iterator design patterns?
Iterator design patterns are used to provide a way to access elements of a collection sequentially without exposing its underlying representation.
Can you give me an example of how to implement an iterator?
Sure! In Python, you can create an iterator by defining a class with __iter__()
and __next__()
methods.
What are the benefits of using iterator patterns?
They promote loose coupling, allow for easy traversal of complex data structures, and can simplify code.
Are there any drawbacks to using iterators?
One drawback is that they can introduce additional complexity, especially if not implemented carefully.
