AddReturnMessage
Zusammenfassung
Sets the return message of a script tool as an output message by index.
Beschreibung
There are times when you may want to return all messages from a tool you've called, regardless of message severity. Using the index parameter, AddReturnMessage will return a message from the last tool executed. The severity of the message (warning, error, and so on, is preserved).
Geoprocessing error numbers shown in the progress dialog box are hyperlinks to a help page that further describes the error. To enable hyperlinks for errors in your script, use the AddReturnMessage function instead of the AddError function, as follows:
import arcpy try: result = arcpy.GetCount_management("c:/data/rivers.shp") except: # Return Geoprocessing tool specific errors # for msg in range(0, arcpy.GetMessageCount()): if arcpy.GetSeverity(msg) == 2: arcpy.AddReturnMessage(msg)
Syntax
AddReturnMessage (index)
Parameter | Erläuterung | Datentyp |
index |
The message index. | Integer |
Codebeispiel
AddReturnMessage example
Returns all messages from the last tool executed as script tool output messages.
import arcpy from arcpy import env # Set current workspace # env.workspace = "C:/Data/MyData.gdb" # Call the buffer tool from the Analysis toolbox. # arcpy.Buffer_analysis("Roads", "RoadsBuff1000", "1000 feet") # Return the resulting messages as script tool output messages # x = 0 messageCount = arcpy.GetMessageCount() while x < messageCount: arcpy.AddReturnMessage(x) x += 1
