What are the performance benefits of using itertools in Python?

Using itertools can significantly improve performance by providing memory-efficient iterators, allowing for lazy evaluation.

Can you give me an example of how itertools can save memory?

Sure! Instead of creating a large list, itertools can generate items on-the-fly, which reduces memory usage.

Are there specific functions in itertools that are particularly useful?

Yes, functions like count, cycle, and chain are great for creating efficient loops and combining iterables.

How does itertools compare to regular loops in terms of speed?

It can be faster because itertools avoids the overhead of creating and storing intermediate lists, especially with large datasets.
