hou.Geometry.createBezierCurve
> Create a new Bezier curve with the specified number of vertices and return it. You would typically call this method from the code of a Python-defined SOP.

def createBezierCurve(num_vertices : int = 4, is_closed : bool = False, order : int = 4) -> hou.Face:

hou.Geometry
Bezier curve
