ERROR 000670: output Output Feature Class is same as input Input Features

Good day,

What should I do to avoid this error

Traceback (most recent call last):

  File "G:\MB\script\", line 37, in <module>

    arcpy.Select_analysis(Input_Features, Output_Feature_Class, Expression)

  File "c:\program files (x86)\arcgis\desktop10.3\arcpy\arcpy\", line 84, in Select

    raise e

ExecuteError: Failed to execute. Parameters are not valid.

ERROR 000670: output Output Feature Class is same as input Input Features

Failed to execute (Select).


This is my code:

# Import arcpy module

import arcpy

# Load required toolboxes

#arcpy.ImportToolbox("Model Functions")

# Script arguments

Input_Features = arcpy.GetParameterAsText(0)

Expression = arcpy.GetParameterAsText(1)

Group_By_Fields = arcpy.GetParameterAsText(2)

NOMBRE__Value_ = arcpy.GetParameterAsText(3)

if NOMBRE__Value_ == '#' or not NOMBRE__Value_:

    NOMBRE__Value_ = "C:\\Users\\CARLOSH\\Documents\\ArcGIS\\Default.gdb\\NOMBRE_CONSTANTE_%Value%" # provide a default value if unspecified

Skip_Null_Values = arcpy.GetParameterAsText(4)

if Skip_Null_Values == '#' or not Skip_Null_Values:

    Skip_Null_Values = "false" # provide a default value if unspecified

# Local variables:

Output_Feature_Class = Input_Features

Selected_Features = Output_Feature_Class

Value = Output_Feature_Class

# Process: Select

arcpy.Select_analysis(Input_Features, Output_Feature_Class, Expression)

# Process: Iterate Feature Selection

arcpy.IterateFeatureSelection_mb(Output_Feature_Class, Group_By_Fields, Skip_Null_Values)

# Process: Copy Features

arcpy.CopyFeatures_management(Selected_Features, NOMBRE__Value_, "", "0", "0", "0")

can you throw some print statements in so the various inputs and outputs can be evaluated

Thank you for answering ,

this code is good! When you step to a tool it generates the error that I showed, I attached a screen with parameters and output interface and error running.

Este codigo genera un featureclass por registro .

I have no experience in python, I have problems with parameters, which is not the error generating tool.

It would be useful to show what you selected when the tool was being run.  In place of print statements you need to use arcpy.AddMessage( stuff ) to get print-out to the dialog when it is running.  As it stands, it is difficult to determine whether the parameters are correct since you haven't listed them

What are you trying to accomplish?  I see in your code that you are setting the output feature class name to the name of your input feature class, hence the error message.  Are you trying to overwrite an existing feature class with a subselection of itself?
