I love picking on PHP as much as anyone else, but you can write just as terrible code in Python as any other dynamically typed language. Those Django and Rails projects can grow into monstrosities as well.
Also, while Rails is in the same league as Django as far as tools and expressiveness go(expressiveness perhaps more so), Django goes to considerable lengths to enforce style and consistency; it is not taboo to politely tell people that their code is not PEP8 compliant.

Sorry man, I'd rather be an employed LAMP developer, but with a few side projects in Python. It's just a programming language, not a religion. :D
There were so many clients in need of Pythonists in London in 2011-2013 when I was working there that I didn't have the time of day to take care of PHP ones. Also, PHP rates were dying and there weren't a lot of people competing for the Python work so I could keep my day rates nice and juicy.
I can think of a lot of things that beat Zend, Yii and Drupal in terms of code management, security, DRYness of code that's implemented, flexibility, the list goes on.
I can play a little piano, but I'm way better at the bass because it's more fun. I can get work done on a PC, but I get way more done on a Mac because it's easier for me to work with. I can cook with a dull knife, but it's never as much fun as using a good one.
I think it's okay for people who don't really like PHP to publicly admit that, but it often seems to be taken as a religious attack by those on the other end of the spectrum.
