Absolutely! Here's a simple example: (x*y for x in range(3) for y in range(2)) generates products of x and y.
What are the benefits of using nested generator expressions?
They provide a concise way to create iterators without the overhead of creating full lists, saving memory.
Are there any performance considerations I should be aware of?
