I've not used linked lists much so I wouldn't know but yeah, I guess that would work.
Well, Python doesn't have pointers, per se, nor would there ordinarily be a cause to implement your own linked list. It's virtually always best to use Python's own data structures, or at least build upon them.
yes.. but if you needed something fancy like a left leaning red black tree or a concurrent skip list you'd need 'is' to work for you for completeness.
(ps. I know they don't really have "pointers" but in these scenarios you use it like a pointer)
