How do itertools compare to nested loops in terms of performance?

Using itertools can often be more efficient than nested loops, especially for large datasets. It reduces memory usage.

Can you give me an example of how to use itertools?

Sure! For instance, you can use itertools.product to generate Cartesian products without nesting loops.

What are the advantages of using itertools over traditional loops?

It provides cleaner code, better readability, and often improved performance due to optimized implementations.

Are there any scenarios where nested loops are better?

Yes, for small datasets or when you need more control over the loop execution, nested loops can be simpler.
