What are some advanced uses of tuples in Python's collections module?

Tuples are immutable sequences in Python, and in the collections module, they can be used in various advanced ways. For instance, you can use tuples as keys in dictionaries or as elements in sets due to their immutability.

Can you give me an example of using tuples as dictionary keys?

Sure! You can create a dictionary where tuples represent coordinates. For example: coordinates = {(1, 2): 'A', (3, 4): 'B'}. Here, the tuples (1, 2) and (3, 4) are used as keys.

What about using tuples in data structures like namedtuples?

Namedtuples are a great way to enhance tuples. They allow you to access elements by name instead of index. For example: from collections import namedtuple; Point = namedtuple('Point', 'x y'); p = Point(10, 20).

Are there any performance benefits to using tuples over lists?

Yes, tuples are generally faster than lists for iteration and have a smaller memory footprint since they are immutable. This can lead to performance improvements in certain scenarios.
