Something like this?
funcDict = dict( __amn__attributeOne : func1,
__amn__attributeTwo : func2,
...
)
noop = lambda *x : None
object = pm.ls()
for obj in objects:
for attr in obj.listAttr(string="__amn__*"):
func = funcDict.get(attr.plugAttr(), noop)
func()
I'm curious though if this indeed boosts performance. The dictionary look-up
should be faster than multiple if statements...
