I've been doing a lot of job hunting lately. There are a ton of crappy jobs out there for php/java code monkeys. If you can solve FizzBuzz you can get the job, though you might not want to. Python and other more fashionable languages tend to be the choice of more sophisticated teams with higher standards. Simply put, a beginner's level understanding of PHP will get you a php code monkey job. A beginner's level understanding of Python along with an understanding of fundamentals can get you a dev job.

edit: definitely broad strokes
