What are the performance differences between iterators and generators?

Iterators and generators both allow for lazy evaluation, but generators are often more memory efficient.

Can you explain why generators are more memory efficient?

Generators yield items one at a time and only store the current state, while iterators may require more memory.

Are there any scenarios where iterators are preferred over generators?

Yes, iterators can be more suitable when you need to traverse data multiple times or require more control over the iteration process.

How do I implement a generator in Python?

You can implement a generator using the yield keyword in a function. It allows you to produce a sequence of values.
