All that proves is that even expert Python developers can, on occasion, write non-idiomatic Python -- or that they accept code contributed by non-expert Python developers, and don't bother adjusting trivial stylistic flaws. When I learned Pascal 20+ years ago, it took me a long time to stop writing "x not in y" and learn the non-English-like "not x in y". Then I learned Python, and it took me a while to stop writing Pascal code in Python. Bad habits take a while to disappear.
