A Blender Curve Data consists of multiple L{CurNurb}(s). Try converting a Text object to a Curve to see an example of this. Each curve is of
type Bezier or Nurb. The underlying L{CurNurb}(s) can be accessed with
the [] operator. Operator [] returns an object of type L{CurNurb}.
the [] operator. Operator [] returns an object of type L{CurNurb}. Removing a L{CurNurb} can be done this way too. del curve[0] removes the first curve.
Note that L{CurNurb} can be used to acces a curve of any type (Poly, Bezier or Nurb)
