add a callback to MObjectHandle, then you can get every node that is
created regardless of what the command returns. Once you got your nodes,
remove the callback
import maya.OpenMaya as om
import maya.cmds as cmds
cmds.polyCube(n="testCube")
new_nodes = []
def cb_add_nodes(node, data):
new_nodes.append(om.MObjectHandle(node))
id = om.MDGMessage.addNodeAddedCallback(cb_add_nodes)
#setDrivenKeyframe command does not return the anim_curve node
cmds.setDrivenKeyframe("testCube", v=1, at="tx", cd="testCube.ty", dv=1,
ott = "spline", itt = "spline")
om.MDGMessage.removeCallback(id)
for n in new_nodes:
n_name = om.MFnDependencyNode(n.object()).name()
print n_name
