Getting a dictionary item from a list in a dictionary

Suppose I have a dictionary, that then has a list of dictionaries within it:

cslfJson = {'displayFieldName': 'CSLF_ID',
            'features': [{'attributes': {'OBJECTID': '13000', 'CSLF_ID': '08123', 'Area_SF': '5431'},
                         {'attributes': {'OBJECTID': '12000', 'CSLF_ID': '08137', 'Area_SF': '2111'}}]}

How would I call OBJECTID in a print statement? WIle I can print something like this 

print(cslfJson['features'][1]['attributes']['OBJECTID'])

I am trying to print both OBJECTID's like this:

for index in cslfJson['features']: 
    print(cslfJson['features'][index]['attributes']['OBJECTID'])

The above throws a TypeError: list indices must be integers or slices, not dict error, so I am confused on the correct syntax.

You are iterating over the contents of the list, not the indices, so index is itself the dictionary. There are several options to iterate over the indices, or you could use the dictionary that you're being given instead:

for subdictionary in cslfJson['features']: 
    print(subdictionary['attributes']['OBJECTID'])
