python 3.3 x64, install PyOpenGL-3.0.2.win-amd64.exe
then run file:
------------------------------
from OpenGL.GL import *
if __name__ == '__main__':
    pass

I get error:

Thank you for the heads up.  I'm moving over from Pyglet, which evidently
opens a context upon import.
For reference the two file was as below, whre i get the error for the
OpenGL import, this makes sense if you need a context as you say.  Thanks
------------------------------
from OpenGL.GL import *
# or
# from pyglet.gl import *

import ctypes

if __name__ == '__main__':

    ver=glGetString(GL_VERSION)
    print(ctypes.string_at(ver,30))
