i'm on ubuntu maverick (10.10), blender 2.49b, Python 2.6.5 -- a total noob to this

I have "import bpy" at the top of my script. Some bpy methods and properties work for me (e.g., "bpy.data.objects["Cube"]" )

but any code I execute with

bpy.ops....
and
bpy.context....

leads to errors:

AttributeError: 'module' object has no attribute 'ops'
AttributeError: 'module' object has no attribute 'context'

What am I doing wrong??

TIA

You are trying to run new blender code on old blender.
You need the docs for the 2.49 API.

hint: import Blender as B is your friend.

hint: dir(some_module) will show you what is in it.
