[Tutor] If tuple cannot be sorted, then why sorted() on a tuple is fine?

[C W]

As pointed out by someone else, ?sorted
sorted(iterable, key=None, reverse=False)

It seems like the only requirement is iterable. I guess tuple is iterable,
so, it doesn't break the assumption that tuple is immutable.

That's what I see, am I right in that?

Thanks!
