I suppose some scientists. I think python is used in bioinformatics. I think some math and physics people use python. I suppose some people use python to learn "programming" in general. Python would do well as a teaching language. I would think that python would be a good language for data analysis. Anything else? Finance? Web-analytics? SEO?
