Python programming is an aesthetic that needs learning. Many of the worst written, and least maintainable python codebases I've seen are by programmers/teams coming from "proper" languages and don't think they have to learn how to write idiomatic python.
"So, the sad thing is that these poor folks worked much, much harder than they needed to, in order to produce much more code than they needed to write, that then performs much more slowly than the equivalent idiomatic Python would."
I included a link to this blog-post in the "letter of intent" (don't know the exact English term) that I sent to my potential employer just before my first interview for a professional (Python) programmer job, back in 2005. I got the job. Good times.
Best example I've seen was from a couple of Java devs transitioning to python, they re-wrote a system 3 times: 1st time: 35k loc 2nd time: 10k 3rd: 2k
The third rewrite was also significantly faster than the first two :)
