If it's just the command itself that you're concerned about, as
opposed to problems with its arguments, then use 'exists':
exists("setAttr) returns true
exists("3etAttr") returns false
or, from Python:
import maya.mel as mel
mel.eval('exists("setAttr")') returns true
mel.eval('exists("3etAttr")') returns false
