import Blender
from Blender import NMesh, Window

in_emode = Window.EditMode()
if in_emode: Window.EditMode(0)

me = NMesh.GetRaw("Mesh")
faces = me.faces

## Example for editmode faces selection:
selected_faces = []
for f in faces:
  if f.sel:
    selected_faces.append(f)
# ... unselect selected and select all the others:
for f in faces:
  f.sel = 1 - f.sel # 1 becomes 0, 0 becomes 1

## Example for uv textured faces selection:
selected_faces = []
SEL = NMesh.FaceFlags['SELECT']
# get selected faces:
for f in faces:
  if f.flag & SEL:
    selected_faces.append(f)
# ... unselect selected and select all the others:
for f in faces:
  if f.flag & SEL:
    f.flag &=~SEL # unselect these
  else: f.flag |= SEL # and select these
