Python: How to work in the current ODB file?

[RGX124]

Hi,
I am writing a Python program in order to work on the current odb file.
I would like to know how to specify that it should use the current (already opened) odb file, in order to avoid to specify the path of the file in the command db= session.odbs[...].

Do you know the command I should include in the Python file in order not to write a program for each odb file?

See below for the beginning of the Python file.

from abaqus import *
from abaqusConstants import *
import visualization
import xyPlot
import displayGroupOdbToolset as dgo
session.viewports['Viewport: 1'].view.setValues(session.views['Front'])
session.viewports['Viewport: 1'].view.setProjection(projection=PARALLEL)
odb= session.odbs['/local/rkler/Documents/PUF2008/Flexion3pts/flexion3pts-module-C3D20R-Si-iso.odb']
session.xyDataListFromField(odb=odb, outputPosition=NODAL, variable=(('RF',
NODAL, ((COMPONENT, 'RF2'), )), ('U', NODAL, ((COMPONENT, 'U2'), )), ),
nodePick=(('COUTEAU-4', 1, ('[#0:10 #1 ]', )), ), )
...
..
.


Thanks
