I'm not sure why you'd get that error if you installed SolidPython. Did you follow the instructions here?
Once you have done the sudo python setup.py --install step, it should load easily. You can test it by simply opening python and typing "import solid" (ctrl-D to exit). If the module doesn't exist, it simply means it wasn't installed properly.
sudo python setup.py --install
One thing to try is to clone the github repo, and simply put the "solid" directory next to the script. "import solid" will first look for a subdirectory where you are named "solid", and if it doesn't find it, it will go look some place like /usr/local/lib/python2.7/dist-packages/ or /usr/local/lib/python2.7/site-packages/solid. If you have a "solid" directory where you run the script, it won't matter if it installed properly.
By the way, python a wonderful, and simple programming language. Don't be afraid of it :) If you have any prior programming experience at all, it will be fairly straightforward to learn what you need for this.
