The phrase "increasingly ubiquitous" doesn't make sense. Something is either ubiquitous or not. There's no such thing as increasingly infinite, for example.

It's best to avoid passive voice, but sometimes that requires difficult thinking about who is taking action. In this case, who is causing Python to be deployed in more computing environments? How about this revision:

"With increasing frequency, software engineers and system administrators are choosing Python, because the language is easy to learn and productive for developing large, complex applications."

I'm not sure that's how I'd explain Python's popularity.
