move character using python script

I had imported a character model from makehuman to Blender. I can move it by selecting the mesh.
But now, I want to try to move it using scripting and insert keyframe for it.
I try to search this line of code: list[bpy.data.objects] to see what objects that I can used to select.

Then I try to move those objects, but the model won’t move at all. Anyone can give an idea or guide for this? Thanks.
