[Bf-python] 3 quick questions

[Campbell Barton]

Nope, selection and active are separate. this is by design & intentional.

obj = bpy.data.objects["Cube"]
bpy.context.scene.objects.active = obj
obj.select = True

As for adding groups, generally when scripting you don't want
functionality to be mixed up with context the way it is with
operators.

You may add 10 groups, then objects to each one, in this case its
annoying to have to worry about what might be selected when your
scripting a setup like this.

In most cases python functions exist to create and remove data - since
its not normally that nice to do this from operators.
