nuke.createNode hooks up nodes where possible based on the current selection,
opens the node’s control panel (unless inpanel=False is passed), and sets any
knob defaults on the node. It triggers both the onUserCreate and onCreate
callbacks to run, and accepts knob values as a Python string representing a TCL
list.
nuke.nodes.Class doesn’t connect the node, apply any knob defaults, open the
node’s control panel, or trigger the onUserCreate callback, and it accepts
keyword arguments for knob values.
Each method has advantages and disadvantages. You will find instances where
using one is easier, necessary to trigger some behavior, or results in more
succinct code.
To connect the Camera input of a ScanlineRender node, use <node>.setInput(2,
camNode)

Subject: [Nuke-python] creating nodes and connecting them
I started of with nuke python API i am curious to know what is the difference
between the two methods to create node shown below?
Code:
import nuke
mainCam = nuke.nodes.Camera(name="mainCamera")
the above command creates a new camera node, but does not open the properties
panel, however if i use the
Code:
nuke.createNode("Camera")
the above creates camera and shows the properties panel, so what is the
preferred way and what each has advantage over each other?
so what is the best way and secondly if I want to create a scanlineRender node
but it should have mainCamera connected to the cam input of the scanlinerender
node, how would i achieve that ?
