Python Bindings for Python 2.7

it. Installed path of Python 2.7 is

Hello,
I am using python bindings of libvirt. When I use the function

Care to share an R presentation?
The R movement is picking up steam in the center of America. People
that ignored my R-enthusiasm 10 years ago are now calling me up asking
for presentations. I need to make a 2 hour presentation to a
collection of faculty and grad students who might like to use R. I
don't want to make it seem too complicated (as I often do), but I
don't want to mislead them to think it will be easy.
