New submission from Miki Tebeka <[email protected]>:
This way they will behave more like getattr and the dictionary get.
If default is not specified, then if the item/attr not found, an execption will
be raised, which is the current behavior.
However if default is specified, then return it in case when item/attr not
found - default value will be returned.
I wanted this when trying to get configuration from a list of objects. I'd like
to do
get = attrgetter('foo', None)
return get(args) or get(config) or get(env)
