Modifying Python script to work in a toolbox

JacobDrvar — Mon, 15 Jul 2013 17:00:03 GMT

I am new to python scripting and began by creating a specific tool. The clip works well in either PythonWin 2.7 or ArcToolbox 10.1. Now, I want to modify the script for any feature class. How would I modify the script to input/clip/output any feature class? GetParameterAsText? Then, I intend to add the script to a toolbox. The script is as follows:

#Import system modules
import arcpy
from arcpy import env

#Workspace
env.workspace = "E:\User\MillageCode"

#Variables
input = "Sales_2006.shp"
clip = "EagleHarborSales_temp.shp"
output = "Output_temp5.shp"

#Clip the Sales_2006 shapefile to the EagleHarborSales_temp shapefile
arcpy.Clip_analysis(input, clip, output)

#Info
print arcpy.GetMessages()

Thanks!

So, I have modified the Python script to include the GetParameterAsText function. But, I receive an error code that statues values are not defined for the input, clip, and output. The code now reads:

#Import modules
import arcpy, os, sys
from arcpy import env

#Workspace
arcpy.env.workspace = arcpy.GetParameterAsText(0)

#Variables
input = arcpy.GetParameterAsText(1)
clip = arcpy.GetParameterAsText(2)
output = arcpy.GetParameterAsText(3)

#Clip
arcpy.Clip_analysis(input, clip, output)

#Info
print arcpy.GetMessages()

Any suggestions on why the script errors out?

"E:\User\MillageCode"

shouldn't work, you need \\ instead of \ or append r to the front of the path

"E:\User\MillageCode"

The E:\User\MillageCode path works in both ArcToolbox and PythonWin.

Any suggestions on the second script? The error is an ExecuteError: Failed to execute. Parameters are not valid. Error 000735: Input, Clip, and Output Features: Value is required. I thought the values were provided as variables.

print the inputs and outputs to see if what you suggests does indeed work

Dan,

The desired results were achieved through the first script. I loaded the output shapefile created in Python vs. running the clip tool in ArcToolbox. The results were identical. I just NEED to get the second script up and running. Thanks.

This is a copy of the results from the Interactive Window. I just reran the first script.

Are you supplying the script with the requested parameters? In PythonWin there is a place to put in the parameters(Arguments). In toolbox you will have to create the parameters.
