from Blender import Curve, Object, Scene
c = Curve.New()             # create new  curve data
cur = Scene.getCurrent()    # get current scene
ob = Object.New('Curve')    # make curve object
ob.link(c)                  # link curve data with this object
cur.link(ob)                # link object into scene

.... adding some points ....

c = Object.getData() # c - Curve
spline = c[0] # first spline in the curve object
