Rename object using for loop

[danispag]

I have a list of objects which I want to rename. But I want each object to be renamed differently. Image attached as an example.

This is what I did so far but its not working as I want.

Can anyone help me please

Thanks in advance 🙂

lGrpSel = cmds.ls(leftFingers)

chunk_size = 3

leftChunks = [lGrpSel[i:i + chunk_size] for i in range(0, len(lGrpSel), chunk_size)]

side = 'left'
thumb = 'Thumb'
pointer = 'Pointer'
middle = 'Middle'
ring = 'Ring'
pinky = 'Pinky'
order = ['Base', '01', '02']
objType = 'CTRL'
spacer = '_'

for f in leftChunks:
for i in range(0, len(f), 1):
cmds.rename(f[i], side + thumb + spacer + order[i] + spacer + objType)
cmds.rename(f[i], side + pointer + spacer + order[i] + spacer + objType)
cmds.rename(f[i], side + middle + spacer + order[i] + spacer + objType)
cmds.rename(f[i], side + ring + spacer + order[i] + spacer + objType)
cmds.rename(f[i], side + pinky + spacer + order[i] + spacer + objType)

There are many, many ways in which you could achieve this - from almost hardcoded, to something potentially illegible, so I would say it would actually be a great learning exercise.

# Provide variables for grouped naming segments
side = 'left'
descriptors = [
    'Thumb',
    'Pointer',
    'Middle',
    'Ring',
    'Pinky',
]
identifiers = [
    '_base_CTRL',
    '_01_CTRL',
    '_02_CTRL',
]

# Get the selection and break it into groups of 3
selection = mc.ls(sl=True)
sel_chunk = [
    selection[i:i + 3]
    for i in range(0, len(selection), 3)
]

# Iterate the selection groups and descriptor for that group ('Thumb')
for sel_grp, desc in zip(sel_chunk, descriptors):

    # Iterate each item in the selection group along with an index
    for i, name in enumerate(sel_grp):

        # Construct the name. 
        # The modulus operator is very convenient (not to be confused with old-style string formatting).
        new_name = side + desc + identifiers[i % 3]

There are many other ways to do this, but this seemed to closer to the direction you were heading.

Amazing that worked perfectly :). Thank you so much
