I'm not sure I fully understand your question, but perhaps this will help.

I haven't used Windows for anything like this for decades, but I would
expect something like this:


(1) Create a file containing your Python code and call it "myscript.py" (or
any other meaningful name):


from org.RDKit import *
from java import lang
lang.System.loadLibrary('GraphMolWrap')
m = RWMol.MolFromSmiles('c1ccccc1')
m.getNumAtoms()


(2) Create a .bat file which calls Jython. I don't remember .bat syntax, but
perhaps it is something like this?


CLASSPATH=$CLASSPATH:$RDBASE/Code/JavaWrappers/gmwrapper/org.RDKit.jar;
jython -Djava.library.path=$RDBASE/Code/JavaWrappers/gmwrapper myscript.py


And that's it.

Does that work? Any Windows users like to comment?
