IN ANY CASE: It is helpful, to have at least read across the Sikuli docs: http://doc.sikuli.org/

--- As stated in the intro of the docs at http://doc.sikuli.org/:
However, if you would like to write more powerful and complex scripts, which might even be structured in modules, you have to dive into the Python Language
(http://www.jython.org/jythonbook/en/1.0/).

--- A very good and straight forward tutorial on Python language (C-Python! see comment below):
http://www.tutorialspoint.com/python/index.htm

--- If you want to have an interactive interpreter in parallel, that is aware of Sikuli features, while going through a tutorial:
on a command line enter:
java -jar path-to-sikuli-script.jar -i

(where path-to-... has to be adapted for your situation)

--- Since these are more tutorial kind of docs, as a reference you can use:
Python 2.5: http://docs.python.org/release/2.5/index.html (Language and Library reference + much more)
Jython 2.5.2: http://www.jython.org/docs/index.html

--- DIFFERENCES between Python and Jython (Sikuli):
Always be aware, when using Python documentation, that Sikuli uses the Java based Jython interpreter internally, that especially cannot load any Python modules that are written in C or need C-based API's to the underlying system.

So if something, that might work in Python, produces "name not found" errors (or other errors) in Sikuli/Jython, you have to live with the fact, that it will not be available in Sikuli.
