Iterating an ArcGIS tool over multiple Fields with selection boxes

Question

I have one shapefile that contains many fields and I'd like to write a simple script tool that allows me to run IDW for the fields I select. Is this possible?

For example.....

Input: 1 shapefile

Sample  field1  field2  field3  field4 .....
1       26.5    27.5    22.2    32.3  
2       19.1    12.2    45.3    33.3 
3       11.1    15.6    44.4    34.4 

Options:

field 1 ☑

field 2 ☑

field 3 ☑ .....

Output: field1_IDW, field2_IDW, field3_IDW .....

EDIT: The following code works properly

# Import arcpy module
import arcpy
from arcpy import env
from arcpy.sa import *

# Check out any necessary licenses
arcpy.CheckOutExtension("Spatial")

inPointFeatures = arcpy.GetParameterAsText(0)

fieldList = arcpy.GetParameterAsText(1)

# Define local variables
cellSize = 250.0
power = 2
searchRadius = RadiusVariable(12)

for fieldName in fieldList.split(';'):
    outIDW = Idw(inPointFeatures, fieldName, cellSize, power, searchRadius)
    # Save the output 
    outIDW.save("C:/temp/idwout_{0}.tif".format(fieldName))

Answer 1

One option, here is the general code logic:

1. Create a script tool with a Field multi value data type

2. Within the python code, loop through the field list and define the index value as the field parameter within the IDW method

   fieldList = arcpy.GetParameterAsText(0)
   for fieldName in fieldList.split(';'):
       outIDW = Idw(inPointFeatures, fieldName, cellSize, power, searchRadius)
       # Save the output 
       outIDW.save("C:/temp/idwout_{0}.tif".format(fieldName))
