You might want to have a look at this : https://www.sidefx.com/docs/houdini/hom/hou/Node.html#addEventCallback

Have exemple for me please !!

hou.node("/subnet1").addEventCallback((hou.nodeEventType.NameChanged, ), name_changed)

it's error sir

I typed this (the example provided in the link I sent) in the Python Shell and it works fine :

def name_changed(node, event_type, **kwargs):
     print("Geo node is now named %s" % node.name())
 
hou.node("/obj/geo1").addEventCallback((hou.nodeEventType.NameChanged, ), name_changed)

You have to define a function to link to the event callback, and no just copy one line... Note this will work only for the current session, it won't be saved in the file if you close Houdini (as written in the doc link).
