This is my attempt to make the python syntax highlighting in Vim more beautiful
Support Python C/C++
In the syntax folder is the python.vim which does the syntax highlighting for Python. Just replace yours with mine but remember to backup beforehand.
Next I had to add another color definition to the molokai.vim stylesheet. This is probably not a very good idea because the new color definition will not be available for a different color theme. So in your colors folder add this molokai.vim and remember to select it as your default colorscheme.
The additions are still very much a hack job and must be improved upon. I think there are still two issues to sort out to duplicate the functionality of the Textmate highlighting, but I guess it is usable.
