There are good coders, great coders, and just a bunch of awful ones. There's a difference in being able to code something that works, and something that works brilliantly, and even better at scale. That said, readability and good commenting in coding and documentation should apply in any language.

In Python for example, there's kind of a (mostly) default way of doing it. In other languages, not so much. But that doesn't mean the company culture can't push for something like this (a standard, at least to the extent in which a language permits doing so). Developers performance is more base on how they like working in a language (better to find true language agnostic developers), culture fit, personality, etc...

If you're outsourcing, that's a totally different set of traits and number of things to look for than if you're hiring in house (which I would recommend for the core team and in general anyway; hiring in house that is).
