Hello, Your try statement around the import was hiding a small error: you should remove the import event, because there is no event.py. Your try statement around the import was hiding that and another big error: python failed to tokenize such and such, N_TOKENS not defined. The problem there was that you should never name a module the same as a python internal module. Just rename the file tokensprite.py or something, then change your import statements to import tokensprite. Then you can make a token image and in globalvars.py add the missing:
token = load_file(DATADIR+'token.png')
I've attached an example token.png for you that I made in GIMP. I transfer the rights of the image to you.
For future reference, I suggest to never add a try statement around imports unless you plan to show the traceback yourself--otherwise you'll just hide the traceback and never know what is wrong--there is no benefit to your program running if it is missing modules.
Just to let you know, I have made a fork (accidentally based on the earlier google code version) at github.com/poikilos/pylaga where you can learn some more tips (I renamed just about all variables, and put everything in classes so globalvars.py is not needed--there is still more work to be done as of now, such as moving physics and explosions to the world class, formerly the Gamelolz class, so sprite classes don't need access to the world and are instead used by the world--world should also determine whether the sprite hits the side as well so the sprite doesn't need world_rect and so all physics are in one place in world). Changing yours this way probably isn't practical since it took me about 60 hrs, but you could learn from my fork for the sake of future games you may write.

If you use convert_alpha instead of convert (in globalvars.py), you can use PNG transparency so black background is not drawn over things.
