Rename selected objects (ultra-noob)

[are...@gmail.com]

Hey All,

I am just getting started out trying to understand Python (and programming in general). I'm trying to make a simple script that renames all my selected objects. Obviously this should be super simple, but when I run what I have so far, it only renames one object regardless of what is selected.

import maya.cmds as cmds

def renameFun ():

mySel = cmds.ls (selection = True)
newName = "Test_Name"

for i in range (len(mySel)):
cmds.rename(newName + "_%d" % i)

I am calling the function when I run it in Maya. Any help would be very appreciated!

Try this:

import maya.cmds as cmds

def renameFun ():

    for i in xrange ( len ( cmds.ls (selection = True) ) + 1 ):
        cmds.rename("Test_Name_%s" % i)

    return True

# Python starts counting at zero so you will miss the last object without adding a one

# range has been proven to show consistent memory drains, use xrange instead

# That’s a string, not a digit you are adding into the name

# Not sure why it would only ever rename one item, but hope this helps

# Always return at least True, according to PEP8, but if you are new to python don’t worry about that just yet.

If your goal is to rename each item in the selection to an incrementally new name, you probably want to specify each original name as you do it:

import maya.cmds as cmds

def renameFun ():

    mySel = cmds.ls(selection=True)

    newName = "Test_Name"

    for i, orig in enumerate(mySel):

        cmds.rename(orig, "%s_%d" % (newName, i))

"enumerate" is convenient way of automatically getting an incremented counter in addition to each item of your list. It would be equivalent do doing something like:

i = 0

for orig in mySel:

    ...

    i += 1

Thank you both for your reply - I was able to get it working.  I'm glad you mentioned enumerate - I had heard of it, but not thought to use it in this way.

Hi;

for i in range (len(mySel)):

cmds.rename(mySel[i],newName + "_%d" % i)

I think you didn't define the object you need to rename, mySel[i] is you need rename object!

EagleZ, you're right!  It works now...now I understand why my original attempt wasn't working.  Thanks!
