I'm using the following tool in ArcGIS 10 - Calculate Distance Band from Neighbor Count (Spatial Statistics). I'm using a python script to execute this tool several times on different shapefiles:

    import arcpy
    arcpy.env.workspace = "c:/data"
    mindist, avgdist, maxdist = arcpy.CalculateDistanceBand_stats("Blocks1", 1, "EUCLIDEAN_DISTANCE")
    mindist, avgdist, maxdist = arcpy.CalculateDistanceBand_stats("Blocks2", 1, "EUCLIDEAN_DISTANCE")
    mindist, avgdist, maxdist = arcpy.CalculateDistanceBand_stats("Blocks3", 1, "EUCLIDEAN_DISTANCE")

At the moment, this outputs the 3 result values to the Results-Messages window in ArcMap 10, overwriting the past results each time. Is there any way I can write these values to a text file after each execution of the tool using python code. If possible I would like to run this on many shapefiles and write the output values to the same text file. If a text file isn't feasible, then anything that can store this information will suffice.


you can do this with some python bindings as here. You can further enhance the code.

from datetime import datetime

stime = datetime.now()

filename = "path/to/log_%s.txt" % (stime)

if not os.path.exists(filename ):

f = open(filename, 'a')
f.write(stime + ' :  ' + mindist, avgdist, maxdist)

beside this you can use python logging module too. more information here and here...

import logging
logger = logging.getLogger('myapp')
hdlr = logging.FileHandler('/var/tmp/myapp.log')
formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)s')

logger.error('We have a problem')
logger.info('While this is just chatty')

i hope it helps you...

  • Thanks for your reply. I'm very new to python. Where in my script (above) would I put this, and do you think it would fit straight in, or would I need to change some things? – JPD May 22 '12 at 13:10
  • you should read A quick tour of ArcPy here. no they are examples code which have to be revised before adding. – Aragon May 22 '12 at 13:22
  • Is there not a line of code that just puts 'ResultObject' from the tool into a table or similar? – JPD May 22 '12 at 13:28
  • Is the info you want stored in the results window? help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/… If so do you still want a log file? – theJones May 23 '12 at 19:34
