[Qgis-developer] python and OSGEO4W

[Alexander Bruy]

Hi Matteo,

AFAIK, QGIS for Windows platform (both standalone and OSGeo4W)
has "built-in" Python which does not interact/overlaps with other Python
intepreters.

If you need to install pure Python modules, you always can use pip. There
are lot of posts about using pip with OSGeo4W [0-3].

Hope this helps.
