To get a list of sde instances you could do something like this. Not sure if there is a better way. sde_dir =  os.path.join(os.getenv("APPDATA"), r"ESRI\Desktop10.0\ArcCatalog") sde_list = os.listdir(sde_dir)     if sde.endswith(".sde"):         print sde ... View more

Please read this. http://forums.arcgis.com/threads/48475-Please-read-How-to-post-Python-code As to your problem. What are your field names and types? ... View more

Ensure your script only uses UNC paths not mapped drives, the account you are executing the task as has permissions to access an ArcGIS license and your sde connection file is not using OS authentication. ... View more

Put some print statements in to check what it is doing, if it enters your loop with the expected arguments etc. ... View more

Try removing the trailing forward slash. It works fine for me using ArcGIS 10.0 either way though. I'm not even sure why this needs to be part of the arcpy package though, as tlomiej1 said os.makedirs or os.mkdir are already available. ... View more

As a side note, I'd also look at using UNC paths vs mapped drives for network resources. ... View more

I would suggest creating a tableview or permanent table depending on what you want to do with the data, and using a search cursor on that. ... View more

your syntax for the cursor is a little off. The first parameter is the input which is correct, but the second parameter is the where clause which you have populated with your field variable. Also, you don't need to add the next row commands. You want it to look like this. import arcpy import os featureClass = arcpy.GetParameterAsText(0) photo_field = "PhotoHotlink" results_field = "PhotoExists" curs = arcpy.UpdateCursor(featureClass, "", "", [photo_field, results_field]) #row = curs.next() for row in curs:     photo_path = row.getValue(photo_field)     if os.path.exists(photo_path):         row.setValue(results_field, "Y")     else:         row.setValue(results_field, "N")     curs.updateRow(row)     #row = curs.next() del curs, row Actually, you need to include both your reading and writing fields. ...

It depends how you listed your files and passed your variable to the describe tool. If you used anything but arcpy.ListRasters() or arcpy.ListDatasets it won't work as Esri Grids are stored as folders not files. I'm not sure why it would work as stand alone and not in a script tool. ... View more

Remove the second string index reference to the name_field variable in your output line. Should look like this. txt.write("<</T({0})/V({1})>>\n".format(name_field,item)) ... View more

Sorry for being unclear. As I mentioned, ultimately I'm writing values to an FDF file, which will be used in conjunction with a PDF template. The PDF contains fields for each Member, there can be up to 9 members. The fields are named Member1, Member2, etc. through Member9. The line of code that writes the values out is this. Using the field name in the PDF/FDF, and the data from the script txt.write("<</T(FDF Field Name)/V(" + str(arcpy variable name) + ")>>\n") [\code] I have potentially 9 team members, but not always. I may have none or some, not always 9. I'm trying to write these values in a loop. So something like this Loop through the members list create a variable for each item in the list populate that variable with the value from the list write that variableto the FDF file using txt.write so the loop would actually contain the txt.write     for item in lMembers:         FDF_Field_Name = FDF_Field_Name+item         FDF_Field_Name+item = lmembers+string_value         txt.write("<</T(FDF_Field_Name)/V(" + str(FDF_Field_Name+item) + ")>>\n")         arcpy.AddMessage(item) something like that, probably clear as mud now ;) Cheers So would this be an example of the strings you want to pass? FDF_Field_Name = "Member1" item = "Joe" ... View more

What I think you are asking is if you can use selections made interactively in arcmap and pass those to the tool. The answer should be yes as long as you reference the layer with the selection in your tool. I haven't jumped in to addins for 10.1 myself yet but you can achieve this functionality with a regular script tool so I assume the same would hold for the new version. ... View more
