Hello,
I answered your other post on the main SAM support forum:
sam.nrel.gov/node/75222
There are a few differences in the functions that are available from the script editor in SDKtool than its counterparts in the SAM user interface, but you can use the function reference in each: From SDKtool, click Help to open the function reference; from SAM, click Functions.
As I mentioned in the other post, the LK Guide comes with SAM. It's also available in the SDK (lk_guide.pdf) along with the SSC Guide.
Finally, you can use SAM to generate sample code in any of the languages supported by the SDK, including Python. For more on that, including a video demonstrating how to generate code from SAM, see this post on the SDK support forum:

Best regards,
Paul.
