res is a nested *dictionary*. It has the same structure as your configobj.

So how do you want the failures represented ?
You want your nested dictionary of True/False flattened to a list of failures ?

Simple enough... *but*, how do you want nested keys represented in this list ?

Suppose you have a config file that looks like :

Key1 = value1
Key2 = value2
[section]
    Key1 = value1
    Key2 = value2
    [sub-section]
        Key1 = value1
        Key2 = value2

Suppose Key1 in the top level section *and* Key1 in 'sub-section' fail, how do you want to show that ?

I can suggest two options :

['Key1', 'section/sub-section/Key1']
[['Key1'], [['section', ['sub-section'], ['Key1']] ]

The first is 'flatter', the second is arguably more 'accurate'.

It should be easy enough to write a function that iterates over either the res dictionary or your ConfigObj *and* the res dictionary - flattening it to a list.

Would this do what you want ?

All the best,
