  using xrange made it slightly faster That's what I would expect, since xrange works like a generator; but the internals of its implementation in CPython back when the article ran its original tests were evidently less efficient than they are now. the difference was pretty small I suspect that's because the strings being concatenated are really small (the largest will only be 5 bytes for n=10000). I would expect the difference to get bigger as the individual strings get larger.
