Assigning a material in Blender with a script

Question: How do you assign a material with a scrip开发者_如何学编程t to an object in blender?

Info:

I have this script to import a proprietary model type of mine that is basically a star map with object consisting of a single vertex. in order to make them look like stars and be visible they are all going to have a halo material assigned to them. I'm figuring out how to make this material and give it the values just fine, but I can't seem to get it to assign. I tried the most obvious thing which was:

objectName.setMaterial(materialName)

but that did nothing. and when i would take an object that had a material and call the getMaterial function on it, it would return nothing. there is something I'm missing here, can some one shed some light on it? Thanks.

objectName.setMaterials([materials]) --- forgot that little "s".

Where the argument to setMaterials is a list of 16 items or less, all of which must be Materials or None.
