Yes, it is. But due to the way we currently implement the Python bindings, in order to reduce the amount of extra stuff required to run the game, I've drastically reduced the amount of Python Modules available by default. So if you go to the Engine folder and open the Lib folder, you'll see the modules shipped with the engine. In order to access different modules, you need to add them to this Lib folder and resolve the dependencies (adding them too).
Once you've done that, by restarting the engine you should be able to import the new modules just fine.
