Automatically rename objects and their children

Hi, I have an issue,
I have 2000 objects and some of them have children.
At max each object has two more children.
At minimum, objects has one child.

Could someone help in renaming them with Mel or Python?

I want them named for example:
Object1_LOD0
Object1_LOD1
Object1_LOD2

Object2_LOD0
Object2_LOD1

etc.

Thank you.

My wonderful colleague created this script in Python for me. It does exactly what I have described above.
I have attached it.

import maya.cmds as mc
import os

def rename_lod(path, name, n):
if "LOD" in name:
name = name[:-5]
print "Renaming", path, "to", name
rels = mc.listRelatives(path, children=True, fullPath=True)
print rels
if len(rels) == 1:
mc.rename(path, name+'_LOD'+str(n))
return
elif len(rels) > 2:
print "Too many children in one layer"
os.exit(1)
else:
child = rels[1]
rename_lod(child, name, n+1)

mc.rename(path, name+'_LOD'+str(n))

sel=mc.ls(selection=True)

for each in sel:
try:
name = each.split('|')[1]
except:
name = each
rename_lod(each, name, 0)
