The v2.6.4 version of the tutorial says this:
Is that really true in CPython? It seems like you could advance the pointer instead of shifting all the elements. It would create some nuances with respect to reclaiming the memory, but it seems like an easy way to make lists perform better under a pretty reasonable use case.
Something like this was one proposed (ie, leave space at both ends of a list) but was rejected as over-complicating the list implementation for *relatively* rare use cases. I believe deque was written subsequently to address such other use cases.
