You're trying to read the string "data.txt". What you want is to open and read the file.
import json
with open('data.txt', 'r') as data_file:
json_data = data_file.read()
data = json.loads(json_data)
Try:
data = json.load(open("data.txt", 'r'))
json.loads interprets a string as JSON data, while json.load takes a file object and reads it, then interprets it as JSON.
I did json.loads(json.loads(string)) and was able to get the dictionary. You can check it out. The first time it doesn't just return the same string, but processes it (e.g. removes \\ characters).
Ok first you should print your object so that you can read it:

From looking at this you can see that output is a list which contains a single dict. To access this you need:
>>> first_elem = output[0]
You will also see that the hashtags key in the first_elem is contained in a second level dict under the key entities:
>>> entities = first_elem['entities']
>>> pprint(entities)
{'hashtags': [],
'symbols': [],
'urls': [{'display_url': 'isthereanappthat.com',
'expanded_url': 'http://www.isthereanappthat.com',
'indices': [16, 38],
'url': 'http://t.co/QDVYv6bV90'}],
'user_mentions': []}
Now you are able to access hashtags:
>>> entities['hashtags']
[]
Which just happens to be the empty list.
To convert to JSON, note the comment:
>>> import json
>>> # Make sure output is the list object not a string representing the object
>>> json_string = json.dumps(output)
>>> jason = json.loads(output)
>>> jason[0]['entities']['hashtags']
[]
I think your problem is that you made output a string before you json.dumps it, meaning that json.loads will return a string, not a json object.
And @Dan's answer is correct, this is not valid JSON. It is however a valid python dict, and I'm assuming that you got it from Twitter using python then printed it.
