There were a set of Python bindings for phantom.js named PyPhantomjs, and it was included in actual phantom releases, but the maintainer moved away from the project, no-one stepped forward and it was ultimately removed from the project (https://github.com/ariya/phantomjs/issues/10344).

So this project is really useful.

Here's the source code, if you are interested:

Ariya Hidayat & co have put a monumental amount of effort into exposing the inner workings of webkit in phantomjs - I'm not sure I see the necessity for a python rewrite. Taking a quick look at the code, most everything I use phantomjs for outside of screenshotting is not available. A great start for sure, but unless there are some fundamental shortcomings with phantomjs that I'm unaware of, I agree with boothead that python bindings are probably the way to go.

One thing that jumps out at me is that phantompy uses Qt5 internally, while phantomjs uses Qt4. There are lots of new WebKit features and optimizations in Qt5.

phantomjs will target Qt5 in the next release, 2.0.
