Needing some help with MEL Script~

Zunabi

Hello lovely peeps,
  I'm very new to writing scripts but have always wanted to get more into it!
I'm currently trying to write a MEL script that selects all objects with the suffix of hg in the mesh name, adds the existing lambert to all, polySoftEdges everything, deletes input history, and cleans up the scene. I've added the lambert mat part specifically due to work reasons heh-

I'm having problems with trying to figure out a way to get polySoftEdge to work. Currently when I run this script:

select -r "hg*";

sets -e -forceElement initialShadingGroup;

polySoftEdge -a 180 -ch 1;

delete -ch;

performCleanUpScene()

it gives me the Error of how line 3 Doesn't work with multiple objects selected.

Is there a way to get around this?

Much appreciated and thank you for your time~

Or better yet, if easier to do in python (tho I haven't figured out how to translate sets -e -forceElement initialShadingGroup into python yet..)
import maya.cmds as cmds
import maya.mel as mel
cmds.select("*hg*");
models = cmds.ls(sl=True)
for m in models:
    cmds.polySoftEdge( a=180 );
cmds.delete(all=True, ch=True);
mel.eval("cleanUpScene 3")

It still does the same thing with the error of doesn't work with multiple objects selected.
Either response in MEL or Python would be much appreciated~

(Don't have access to Maya atm to test) but you can just select each mesh in your for loop. Also, you don't need semicolons in Python, FYI.

for m in models:

    cmds.select(m)

    cmds.polySoftEdge(a=180)

Try this

import maya.cmds as cmds
import maya.mel as mel

#Get all the transform nodes that have hg in it's name
geo_list = cmds.ls('*hg*',type='transform')

#run through all the geometry
for geo in geo_list:
    
    #Ch=0 so that the soft edge won't end up in history
    cmds.polySoftEdge(geo,a=180,ch=0)
    
    #Get shapes to assign material to
    geo_shp = cmds.listRelatives(geo,s=1)[0]
    cmds.sets(geo_shp, e=True, forceElement='initialShadingGroup')

cmds.select(cl=1)
mel.eval("cleanUpScene 3")
