Hello, i'm new here and I am attempting to modify attributes of a
shapefile via python I can't seem to get the shapefile to be
updated! Can anyone tell me what i'm doing wrong?
import sys
import osgeo.ogr as ogr
import random
ds = ogr.Open( "dist_google.shp", 1 )
lyr = ds.GetLayerByName( "dist_google" )
lyr.ResetReading()
feat = lyr.GetNextFeature()
while feat is not None:
print str(feat.GetFieldAsInteger("COLOR")), # shows 0
feat.SetField(13,-1)
print "changed to: "+ str(feat.GetFieldAsInteger("COLOR")) #
shows -1
feat = lyr.GetNextFeature()
ds.Destroy()
ds = ogr.Open( "dist_google.shp", 1 )
lyr = ds.GetLayerByName( "dist_google" )
feat = lyr.GetNextFeature()
while feat is not None:
print str(feat.GetFieldAsInteger("COLOR")), # shows 0 !!!!
feat = lyr.GetNextFeature()
