[GRASS-user] Fwd: Python-Loop over points

Hello again,

does anyone have an idea how to do that (described below).
It is like the "Iterator" from the new ArcGIS 10 modeller.
What is the equivalent pyhton command to iterate/loop over
points in a point-file?
Maybe someone can give a python example for my problem below.

Thank you

Betreff: Python-Loop over points


I am performing e.g. the r.stream.basins calcutlation in python:

                      dir = "flow_direction",
                      points = "point1",
                      basins = "output")

that's working perfectly in the case of one single point in "point1".
How can I do that multiple times when the point layer consist of e.g. 5
points and I want to create an output for each point (create 5 output rasters).

How can that be done in a python script?

thank you
