mag_subset__2_ != mag_subset___ That's most likely your main problem. Exporting models to python rarely works as intended raw, it gives you a good framework on which to build. ... View more

There is no way to code a pop up window without import a gui module like tkinter. He may be using a simple run with parameters button, which is just an option in most moderately advanced python IDEs, and has nothing to do with your code. ... View more

Doesn't matter, it is a basic tool available in any recent python package. You just use your arcgisscripting instance instead of arcpy. http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?id=1867&pid=1865&topicname=Make_Feature_Layer_(Data_Management ... View more

Hi Dave, I tested Jake's script and it works fine for me. Are you using proper syntax/indentation? Is there a field called "OBJECTID"? Do you have write access to that directory on Y-drive? Not sure what would be causing this issue. Try something simple like rows = arcpy.SearchCursor("parcels") for row in rows:     print row.getValue("OBJECTID") Then add on line by line until you run into a wall. ... View more

I suspected that might happen, your fc variable is a feature class and has no attribute STFID. It is simply a unicode reference to the feature class in the list. Does each block feature class have a single unique STFID value? You will have to retrieve that value somehow, either assigned manually, read from a field the same way you do with the roads, or some other way. If you don't understand this concept you should try some more simplistic operations to get a grasp of basic arcpy functionality. Esri has some good free online training courses to get you started. Try working through this, it gives a great intro to arcpy and python in general. http://training.esri.com/gateway/index.cfm?fa=catalog.webCourseDetail&courseid=1868 ... View more

You have to add your script as a script tool if you want any kind of interactivity with user input, outside of command line parameters as you have already seen. If you do not add your script as a script tool, nothing will pop up asking you to choose anything, unless you design your own GUI to do so. ... View more

So you mean you want to add a shapefile to your TOC? I think people were confused because opening and adding a shapefile mean two different things to most people. What you want is arcpy.MakeFeatureLayer_management(yourShapefile, "TOC name") arcpy.RefreshActiveView() ... View more

Holding the selection as a variable is unnecessary, Update Cursor will "see" selections and process on those only (when referencing a selectable layer of course). This should work, I am not sure what you are trying to do with the row.STFID = fc.STFID line though. import arcpy #Set geoprocessing environment arcpy.env.workspace = r"I:\Dr. Hines\New File Geodatabase.gdb" arcpy.env.overwriteOutput = True #Create list of all blocks fcList = arcpy.ListFeatureClasses("*blk00") highway = "Analysis Roads" #Create loop for fc in fcList:     arcpy.SelectLayerByLocation_management(highway,"HAVE_THEIR_CENTER_IN", fc)     rows = arcpy.UpdateCursor(highway)     for row in rows:         row.STFID = fc.STFID         rows.updateRow(row)     del row     del rows ...

I would recommend something as follows. You could use the getValue instead of row references too. Format where statement as needed. where = "\"Land_Area\" > 0" rows2 = arcpy.UpdateCursor(parcels, where) for row2 in rows2:     row.UTC10_Pct = row.UTC10_Ft / row.Land_Area     rows2.updateRow(row2) ...

As far as I know, the calculate field tool processes on the entire field, not on your current search cursor selection. I could be wrong. Why not use update cursor? Much better than calculate field. And why not use a selection instead of a search cursor? ... View more
