SetSeverityLevel

Summary

Used to control how geoprocessing tools throw exceptions.

Discussion

If SetSeverityLevel is not used, the default behavior is equivalent to setting the severity_level to 2; that is, tools will only throw an exception when the tool has an error.

Syntax

Parameter	Explanation	Data Type

Code Sample

SetSeverityLevel example

Use SetSeverityLevel to force tool to throw an exception when a tool warning is encountered.

import arcpy
from arcpy import env

fc1 = 'c:/resources/resources.gdb/boundary'
fc2 = 'c:/resources/resources.gdb/boundary2'

# Set the severity level to 1 (tool warnings will throw an exception)
#
arcpy.SetSeverityLevel(1)
print arcpy.GetSeverityLevel()

try:
    # FeatureCompare returns warning messages when a miscompare is
    #  found.  This normally would not cause an exception, however, by 
    #  setting the severity level to 1, all tool warnings will also 
    #  through an exception.
    #
    arcpy.FeatureCompare_management(fc1, fc2, "OBJECTID")
except:
    print arcpy.GetMessages()
