I agree with your advice not to abuse lists, but not for the reason you
give. The memory overhead of a linked

Before I answer your question, I should say that you can go a LONG way

There's also the collections.deque for other related purposes.
(I suggest people willing to look at some nice C code to read the
sources of deque, Hettinger has created some refined code, very

That surely depends on the data structu

Yes, lists are implemented as dynamic arrays (but you shouldn't

You should treat Python lists as an opaque item. You shouldn't concern
yourself with the implementation details. Python li

I'd use xrange there. Anyway, I have always felt that Python syntax

It's not a copy, it's a view:
