Python Script failing to execute IDW_sa

[sethdocherty]

I'm currently doing a research project for school which requires me to interpolate recorded temperatures within in our study area. After the maps are made, I'm going to string them together into an animation to show temperature variations over time. I will end up having over 1000 maps interpolated so its out of the question to do them one at a time. I'm in the process of creating a script to automate this. To make the process of coding easier for myself, I created a setup in the model builder, which i ran successfully, and exported the code to python. My problems arises here... I run the code and get these errors:

Traceback (most recent call last):
File "C:\Python25\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", line 325, in RunScript

Here is my code for reference:

The input parameters are missing. Currently this script is using sys.argv[0] for both parameters. The first value in sys.argv is always the name of the script (which explains your error message).

Use:

sensorlocation_shp = sys.argv[1]

...for your input shapefile and:

test1 = sys.argv[2]

for your output raster. Since you're already invoking the geoprocessor object, you can also use:

sensorlocation_shp = gp.GetParameterAsText(0)

...and:

test1 = gp.GetParameterAsText(1)

I totally forgot about this thread until the other day.  I thought I'd post my script that worked. It may be useful to some.
