Outside of your function, you're in ArcGIS world - so you correctly use "!DOC_NO!" to reference the field, which passes each value, then "docno", to the function one at a time. Inside the function, you're in Python world, so you use the variable "docno". def myfunction(docno) :    if len(docno)== 0 :      return ""    else:      return "V:\Eng\Land Management\Easements\Scanned Documents\" + docno + ".tif" edit: also, check your quotes after the first return - you've got two single quotes, then a double quote. ...

expression = "ACCTEXT = '"+p+"'" This probably isn't the problem, but is the above 'p' supposed to be 'pu'? I assume the problem is either there is no data frame called "Main Map" or there is no layer called "TAXPARCELS". Which line is throwing the error? ... View more

I keep getting the following error IndexError: list index out of range. Not sure what I am doing wrong. Might sound silly, but the only thing I can think of is that you haven't entered a value for the parameter, sys.argv[1]. Have you (ie. when you run the script, do you indicate which folder you want?)? Does this work? It should. import arcpy, sys arcpy.AddMessage(sys.argv[1]) print(sys.argv[1]) ... View more

Did it say something like "myraster.tif does not exist or cannot be found"? I'm not sure why but after one or two times, I have to restart Arc to get it to do more. ... View more

Try this: Con(IsNull("myraster"),0,"myraster") This works in the Raster Calculator, for v10, with ESRI GRIDs. Not sure if it's the same for v9.3, or for other formats. ... View more

Haha, now that I look at it "*.14.tif" wouldn't work even if it used wildcards - there's an extra '.' So, touché. ... View more

Jook, you need the second list (inRasters = []) so that you have an empty place to put the rasters ending in "14.tif". "rasterFiles = arcpy.ListRasters()" lists all of the rasters, then put the "14.tif" files into "inRasters". Then, calculate the mean of all of the rasters in "inRasters". The way you have modified the code will produce the original list of all rasters, plus any file in "14.tif", so you'll have two copies of each "14.tif". Finally, just to be clear you are not excluding the files ending in "14.tif", you are only using them (ie. you are excluding anything not ending in (14.tif") ... View more
