Hope this is helpful.
//MEL global proc string[] nozo(string $a, string$b ){ return {$a,$b}; } //nozo("great","day")
#Python import maya.mel as mel #calling a Mel function in python cmd = "nozo" arg1 = '"Great"' arg2 = '"Day"' melCallString = "%s(%s,%s)" %(cmd,arg1,arg2) print melCallString ##### result = mel.eval(melCallString) print result #['Great', 'Day']
(Note its probably cleaner to write all the code in Python)
cheers,
Nate
