Handle specific error in arcpy

Question

I am have a question pertaining to handling specific errors in arcpy 3.7. I want to capture the specific ERROR 000466: does not match the schema of target . The following code narrows it down to the arcpy.ExecuteError, but I cannot find a graceful method to further identify the error as ERROR 000466. The sys.exc_info()[1] returns the entire error value but I would just like the error number without having to parse the string. try: my code here... except arcpy.ExecuteError: e = sys.exc_info()[1] print(e) except: handle of other errors

I can't easily recreate the ExecutionError exception but one thing I would try is to see what you get with the exception's 'args' property, which will give you the arguments passed in by the ESRI code when the exception was created.

try:
   my code here...
except arcpy.ExecuteError as ex:
   print (str(ex.args))  # Maybe the specific error code is one of the args ??????
   e = sys.exc_info()[1]
   print(e)
except:
   handle of other errors

Seems like arcpy.ExecuteError has only two public attributes: args and with_traceback(). You probably won't get around parsing the string.

try:
    arcpy.management.Append(fc_wrong_schema, target_fc)
except arcpy.ExecuteError as e:
    if "ERROR 000466" in e.args[0]:
        # handle
        print("DELETE FEATURE CLASS")
    else:
        # handle or raise
        raise
except:
    # handle or raise
    pass
