You cannot prevent people from doing stupid things anyway. What you can do is encourage good style, and making the "right way" the path of least resistance. You can write readable code in any language, even Perl, if you use enough effort and discipline, but Python tries to make readable code the easy default.
The "quote" you made up is not representative of the Python culture or the article here, although I'm sure you can find some blogger somewhere with that attitude. They seem to have mostly migrated to other more hip languages though.
