#7 Python

Python is a widely used general-purpose, high-level programming language. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in languages such as C. The language provides constructs intended to enable clear programs on both a small and large scale. Known for its clean and efficient code, Python is used by players as notable as Google and NASA. It's also what Dropbox is written in. In fact, the technology is so important to Dropbox that the company hired Python author Guido van Rossum away from Google late last year.  Dropbox isn't the only one hiring Python talent. There are currently 19,455 Python job listings on Indeed.com.
