Hello William,
I tried your nPython.exe, yes, it works on my raspberry.
Could you explain, what you did to create this python-version? Did you
compile it on Windows?
And how would you add modules like numpy etc?
I am sorry if these questions sound silly, but I have no experience with
compiling python from scratch.
Thanks a lot for your support so far
Daniel
