Lock transforms on selected nodes

for node in hou.selectedNodes():
    node.parm("tx").lock(True)
    node.parm("ty").lock(True)
    node.parm("tz").lock(True)
    node.parm("rx").lock(True)
    node.parm("ry").lock(True)
    node.parm("rz").lock(True)
    node.parm("sx").lock(True)
    node.parm("sy").lock(True)
    node.parm("sz").lock(True)

print node.name(), "Locked!"

Change selected nodes to a red colour

nodes = hou.selectedNodes()
color = hou.Color([1,0,0])

for node in nodes:
    node.setColor(color)

Check Environment Path

import os
for i in os.environ["PATH"].split(":"):
    print i

Look for a specific name in all nodes in houdini

name = hou.ui.readInput("Type Name", buttons=('OK',"Cancel",))

if name[0] == 0 and len(name[1].replace(" ", "")):
    print "START..."
    for each in hou.node("/obj/").allSubChildren():
        if name[1] in each.name():
        print each.path()

    print "DONE!"

Get the path to the current network location

local = hou.ui.paneTabOfType(hou.paneTabType.NetworkEditor)
localP = local.currentNode().path()
print localP

Find child nodes

import hou nodes = hou.selectedNodes()

for node in nodes: 
    #print (node,"\n")
    for child in node.children():
        print child

Basic display message UI with custom icon

hou.ui.displayMessage("Your Message", severity=hou.severityType.ImportantMessage)

Get the Network Editor Tab

hou.ui.paneTabOfType(hou.paneTabType.NetworkEditor)
