The single/double quoting could do the job, but in my local test the escape
character "\" works.
//MEL
global proc createSphere(string $name){
sphere -n $name;
}
#PYTHON
import maya.mel as mel
cmd = "createSphere \"test\""
mel.eval(cmd)
I tested this with a simple function - perhaps custom commands with flags
work differently...
