There's a difference between not being able to work in Python, versus not being willing to work in Python. C, perl, ruby, php, even Java would be more appealing to me than touching Python with a ten-foot pole.

Also, presumably you want proficient developers working on the codebase. There's a difference between being able to pick up Python when you have to, versus understanding Python idioms and coding efficiently and bug-free.

ETA: this is getting WAY off-topic, and so I won't continue this thread. If you're interested in why someone wouldn't like Python, there are fires from the holy wars visible clearly from Google that you can go investigate.
