What are the best practices for using itertools in Python?

When using itertools, it's best to understand the specific functions you need, like count, cycle, and chain. This helps in optimizing performance.

Can you give me an example of using itertools to create combinations?

Sure! You can use itertools.combinations(iterable, r) to generate all possible combinations of length r from the iterable.

What about using itertools with large datasets?

For large datasets, prefer using generators from itertools to save memory. Functions like islice can help you process data in chunks.

Are there any common pitfalls to avoid?

Yes, avoid using itertools functions that return infinite iterators without proper termination conditions, as they can lead to infinite loops.
