ExecuteError 异常示例

在下面的代码中，ExecuteError 类用于专门处理任何由 CopyFeatures 导致的地理处理工具错误。

import arcpy

in_features = "c:/base/transport.gdb/roads"

try:
    # Note: CopyFeatures will always fail if the input and output are
    # the same feature class
    arcpy.CopyFeatures_management(in_features, in_features)

except arcpy.ExecuteError:
    print(arcpy.GetMessages())
