I was able to delete my response which was a wholly contained subset of 
this one. :)


But I have one extra question. Is string indexing guaranteed to be 
constant-time for python? I thought so, but I couldn't find it 
documented anywhere. (Not that I think it practically matters, since it 
couldn't really change if it weren't for all the reasons you mentioned.) 
I found this which at details (if not explicitly "guarantees") the 
complexity properties of other datatypes:
