返回值

数据类型说明
Integer

严重性级别。

  • 0 —即使工具生成错误或警告，也不会抛出异常。
  • 1 —如果工具生成警告或错误，将抛出异常。
  • 2 —如果工具生成错误，将抛出异常。这是默认设置。

代码示例

GetSeverityLevel 示例

使用 SetSeverityLevel 可强制工具在遇到工具警告时抛出异常。

import arcpy

fc_1 = 'c:/resources/resources.gdb/boundary'
fc_2 = 'c:/resources/resources.gdb/boundary2'

# Set the severity level to 1 (tool warnings will throw an exception)
arcpy.SetSeverityLevel(1)
print("Severity is set to : {0}".format(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
    #  return an exception.
    arcpy.FeatureCompare_management(fc_1, fc_2, "OBJECTID")

except arcpy.ExecuteWarning:
    print(arcpy.GetMessages(1))
except arcpy.ExecuteError:
    print(arcpy.GetMessages(2))
