> no good reason It's a trade-off. You can compute everything in C, or some things in python. In the former scenario you're trading off software engineering cost with computational efficiency. Since software engineering is insaaaaaanely expensive (I code stupid stuff all day and am paid $150k/y) and processors are dirt cheap compared to them, it makes a lot of sense to do some computing in python/ruby/javascript.
