Sure. The easiest way to do it is to loop over each name and call
objExists(). If we had a massive list of items and wanted to reduce the
maya calls, we could do something more complicated with a single call to
ls, but that is for another time...
items = ["foo", "biz", "baz"]for item in items:
if cmds.objExists(item):
print item, "exists"
else:
print item, "does not exist"
For now, let see if am able to convert that to mel.
