What are some advanced techniques for tuple unpacking in Python?

Advanced tuple unpacking in Python includes techniques like nested unpacking, using the asterisk (*) for variable-length tuples, and unpacking in function arguments.

Can you give me an example of nested tuple unpacking?

Sure! For example, if you have a tuple like ((1, 2), (3, 4)), you can unpack it as follows: ((a, b), (c, d)) = ((1, 2), (3, 4)).

What does the asterisk (*) do in tuple unpacking?

The asterisk (*) allows you to capture multiple elements in a tuple. For instance, a, *b, c = (1, 2, 3, 4) results in a=1, b=[2, 3], and c=4.

Are there any performance considerations with tuple unpacking?

Yes, while tuple unpacking is convenient, excessive unpacking or using it in performance-critical code can lead to overhead. It's best to use it judiciously.
