python - AttributeError: 'NoneType' object has no attribute 'get' while checking none data in list of dictionaries

Question

i am trying to check null fields in dataframe but getting error while trying to compare.

                if data[D]['obj1']['obj2'] is None:

But getting this error AttributeError: 'NoneType' object has no attribute 'get'

data is a list of dictionaries.

"u""obj1":{
     "u""obj2":"None" }

this is how json looks like.

I need to check if that field is none and replace it with empty string.
