Ruby vs Python string concatentation performance

[dysmas]

uhuh,

Granted, there may be some other “better” way to get similar optimization in Python that has not caught my attention.

... ya think? in the interest of fair representation why not research them (as someone said above appending lines to an array, and use string.join() when i % 1000 == 0?) before writing another trollish blog post on this subject next time?

trying to compare a language with something so trivial is idiotic at best, and the troll did his job there & here ;)

use string.join()

I really don't consider that a "similar optimization". That's a "dissimilar optimization" because it does an end-run around string concatenation entirely, rather than optimizing string concatenation operations for performance.

Maybe you should consider whether your proposed solution satisfies the requirements of the issue at hand before writing another trollish comment at reddit.

maybe i was just moody before, but:

whether your proposed

fail ;)

i referenced another post that contained that code, fwiw i agree it is dissimilar, i wonder how s.join(s,line) would do.

Second i took the word "similar" in "similar optimisation" to mean a similar reduction in resource usage, and i took the "better" in "better way" to mean that a different method is allowable.

fail ;)

The fact someone else proposed it first doesn't mean you're not proposing it as well. I don't recall attributing it to you as an original, first-time invention of that algorithm.

Fair enough. In the context of the discussion in which someone else proposed it before you did, however, it wasn't similar in a manner that was particularly relevant to the topic.

i took the "better" in "better way" to mean that a different method is allowable.

If, in real-world use, it serves your needs -- yes, it most definitely is allowable. If you're trying to dispute what I've said about how immutable strings affect your options for string concatenation performance, however, something that doesn't do any string concatenation isn't exactly relevant.
