Ruby is ok. But Perl is million times a better language than Python.
Python is an extremely overrated language.
You haven't addressed my (implied) question,though. I don't think that the average Perl programmer is an order of magnitude more productive than the average Python programmer.
I'm guessing you're more familiar with Perl, because I personally find it hard to believe that Perl by itself is an order of magnitude more efficient to write than Python or Ruby.
