If you switch from model builder to python scripting, there is a module called 'logger' which will allow you to capture and write data to a file. import logging logging.basicConfig(level=logging.DEBUG,                     format='%(asctime)s %(levelname)s %(message)s',                     filename='/tmp/myapp.log',                     filemode='w') logging.debug('A debug message') logging.info('Some information') logging.warning('A shot across the bows') See http://docs.python.org/release/2.6.4/library/logging.html for further details.  Another good resource to look at is: http://blog.doughellmann.com/2007/05/pymotw-logging.html ...

Hey Tommy, In your example of Hour < 6 and you want the next value, would you say your have unique values, or do you want a list of unique values, then create ranges off of that list?  If that is the case, try using the Fequency tool set and set the field to the Hour field or whatever field you want the unique list of values to. You can then use a search cursor on that table to get a complete list of values and easily select the next lowest value by sorting your list. ... View more

Check your field values to ensure that there are no ascii values, you can use the encode() method to remove values that will cause your script to fail. Example: value = sRow.getValue(field.name).encode('ascii','ignore') All ascii values will be ignored.  You can also replace the values. See http://docs.python.org/library/stdtypes.html for more information. ... View more

You might be able to use the bincount() function on numpy to do what you are looking for: http://docs.scipy.org/doc/numpy/reference/generated/numpy.bincount.html the values have to be non-negative though. ... View more

Tom, You cannot change that property via python in ArcGIS 10. The best thing to do is set the 'Fixed Scale' option to 'Automatic' manually. ... View more

If you are running this script outside of an ArcMap session, it will fail due to the fact that "CURRENT" only works when inside arcmap.  Try changing the following: mxd = arcpy.mapping.MapDocument("CURRENT") #set mxd to current map to the path of the arcmap document: mxd = arcpy.mapping.MapDocument(r"c:\temp\mymapdoc.mxd") #set mxd to current map Hope this helps. ...

It's not a quirk, the function returns a list object.  In order to access the underlying data inside the list, you need to tell the object what information you need by letting the list know I want some piece of information in position X. To be even more general, functions return a specific data type.  Hope this helps. ... View more

Jelmer, The reason you are seeing all the white space in your tiff is because you are exporting the page layout, not the actual tiff.  Try specifying your data frame and try it again. Help document: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00s300000009000000 Example: import arcpy mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd") df = arcpy.mapping.ListDataFrames(mxd, "Transportation")[0] arcpy.mapping.ExportToTIFF(mxd, r"C:\Project\Output\ProjectDataFrame.tif", df,                            df_export_width=1600,                            df_export_height=1200,                            geoTIFF_tags=True) del mxd ...

Some suggestions: - You should move your del statement inside your feature class list loop.  - Make sure your environmental workspace is set: arcpy.env.workspace = r"path" - use setValue() on your update cursor - when you join a table, the field names change - Try making the join permanent and using the update cursor (use copy features) on the newly created feature class.  I would also set arcpy.env.overwriteOuput = True. Hope this helps. ... View more
