I think you can also use PySide/PyQt, because they have a browser core of qtwebkit, you can control the browser to open pages, simulate human actions(fill, click...), then scrape data from pages. FMiner is work on this way, it's a web scraping software I developed with PySide.

Or you can try phantomjs, it's an easy library to control browser, but not it's javascript not python lanuage.
