Hello,
Probably that is better for the wingrass mailing list then for the general
grass-user list:
I wrote a python script for grass involving several python modules (numpy,
scipy and matplotlib) and I tested it successfully on my mac osx (GRASS GIS
6.5, Python 2.6.6 and other modules).
Now I'd like to test it on a Windows 7 machine and need to install all the
necessary python modules. So my question: Which python version (2.6.6 or 2.7)
should be installed and which version of wingrass (script should work on all
recent versions of grass). Will Wingrass use the before installed python
(either 2.6.6 or 2.7) and its addtional modules?
What is the simpliest way to make this combination working? Just install
everthing?
thank you
/johannes

Use whichever version of Python you want, but be sure to eliminate all
traces of the Python version which gets bundled with WinGRASS
(including removing any references from environment variables set by
Init.bat).
Once you have a proper Python installation, the only connections
between GRASS and Python should be:
1. GRASS_PYTHON should be set to the complete path to the Python
interpreter. This is used for running wxPython code, e.g. from g.gui
or when running a command without arguments (or with the --ui flag)
displays a parameter dialog.
2. PYTHONPATH needs to contain %GISBASE%\etc\python so that e.g.
"import grass.script" can find the module.

Okay so what I've done now is:
1) Installed Python 2.7
2) Installed addtional Python modules (Numpy, Scipy, Matplotlib)
3) Installed WinGRASS 6.4.1 (recent package for Windows)
4) Created following environmental variables:
GRASS_PYTHON C:\Python27\python
PYTHONPATH %GISBASE%\etc\python
5) Restarted Windows (don't know if needed)
Now two questions
1) Is everything done correctly and how can I check it (GRASS works, but how to
check if grass can access the python modules (Scipy)?
2) Where do I have to store my python-script to call it from GRASS (bin folder
in the lib in Mac OS)?
