: Used in custom script tools to return a string result to a user interface or web application.
: Retrieves all messages (status, warnings, and errors) from the last tool executed. Geoprocessing with Python
After running a tool, you can capture its status and messages using arcpy.GetMessages() and write them to a .txt file: : Used in custom script tools to return
import arcpy # Define inputs input_features = "C:/Data/Roads.shp" output_features = "C:/Data/Roads_Buffer.shp" buffer_distance = "100 Meters" # Run a geoprocessing tool (e.g., Buffer) try: arcpy.analysis.Buffer(input_features, output_features, buffer_distance) # Open a text file in write mode with open("C:/Temp/GP_Log.txt", "w") as log_file: # Get and write geoprocessing messages messages = arcpy.GetMessages() log_file.write(messages) print("Geoprocessing complete.

Check the error log.") Use code with caution. Copied to clipboard Key Functions for Handling Text in Geoprocessing Log saved
