Embedding V8 can work quite well: https://github.com/sqreen/PyMiniRacer
You probably have to emulate some of the DOM, but you can interact directly with whatever obfuscated/packed scripts in a more lightweight and secure way than driving an entire browser.

connecting languages
First learn what forms computer code can be in. Source code combine js and python or to combine c and C++ object code with a linker or at runtime if you want to shell out and run from the prompt

If you want battle-hardened, I figure you can't do better than V8. Here's a Python wrapper that I've poked at a bit (it's not quite 100% feature-complete but it seems to essentially work): https://github.com/sqreen/PyMiniRacer

Cue libv8-node+mini_racer from which PyMiniRacer was born. It is non-trivial but not as hard as one might think.
The most painful part is the libv8 build system and Google tooling, which makes it an absolute PITA for libv8 consumers that are not Chrome.
This is why the libv8 gem was atrocious to keep up to date and to build for several platforms, and why libv8-node was born, because the node build system and source distribution are actually sane.
