There's just a slight problem with your for loop.

"Ask":
   {"0":[[9.13,30200],[9.14,106946],[9.15,53072],[9.16,58104],[9.17,45589]],
    "1":[[9.14,106946],[9.15,53072],[9.16,58104],[9.17,45589],[9.18,37521]] },

"Bid":
   {"0":[[9.12,198807],[9.11,1110],[9.1,42110],[9.09,84381],[9.08,98178]],
    "1":[[9.13,13500],[9.12,198807],[9.11,1110],[9.1,42110],[9.09,84381]]}

Your for loop just needed to be changed a little.

PS you don't need to specify 'r' when reading the file.

You can also get individual values like this:

>>> for x in data['Bid']['0']:
...     print(str(x[0]) + ': ' + str(x[1]))
... 
9.12: 198807
9.11: 1110
9.1: 42110
9.09: 84381
9.08: 98178

I think you have a couple issues going on here. First, valid JSON doesn't use single quotes ('), it is all double quotes ("). You are looking for something like:

[{
"id":123,
"emotions":[],
"lyrics":"AbC",
"emotionID":0,
"artist":"222",
"sentimentScore":0,
"subjects":[],
"synonymKeyWords":[],
"keyWords":[]
},

{
"id":123,
"emotions":[],
"lyrics":"EFG",
"emotionID":0,
"artist":"223",
"sentimentScore":0,
"subjects":[],
"synonymKeyWords":[],
"keyWords":[]
}
]

Secondly, you need to open the json file for reading and then load it as json. The following should work for you:

with open(read_file) as file:
  data = json.load(file)

with open(write_file, 'w') as file:
  json.dump(data, file)

print(data)

Your example is valid json. [] define json arrays. What you have is an array of objects:

with open("myFile.json") as f:
    objects = json.load(f)

import json

array = '{"fruits": ["apple", "banana", "orange"]}'
data  = json.loads(array)
print(data['fruits']) 
# the print displays:
# ['apple', 'banana', 'orange']

You had everything you needed. data will be a dict, and data['fruits'] will be a list

To import a json file, I recommend using the json libary. In your example, you would first need to import it.

import json

Then you can use

with open('filename.json', 'r') as fp:
    data = json.load(fp)

to get the data. Note that load is different from 'loads' (https://docs.python.org/2/library/json.html). You just need to change 'content' to 'fp' since that is how you referred to your file.

Note that this code stores returns the json as a dict, not as a list, which is different than what you are asking about, but probably what you want to use not knowing more about what you are trying to do.

It's not loading your content basically because it's not a valid json format, try this script:

import json

try:
    file_content = """{"uid": 2, "user": 1}
    {"uid": 2, "user": 1}
    {"uid": 2, "user": 1}"""

    json.loads(file)
except Exception as e:
    print("This is not JSON!")

print('-' * 80)
file_content = """[{"uid": 2, "user": 1},
{"uid": 2, "user": 1},
{"uid": 2, "user": 1}]"""

print(json.loads(file_content))

The result will be:

This is not JSON!
--------------------------------------------------------------------------------
[{'user': 1, 'uid': 2}, {'user': 1, 'uid': 2}, {'user': 1, 'uid': 2}]

Proving that if if you wrap your dictionary into brackets and separate the items with commas the json will be parsed correctly

Of course, If you don't want to tweak your file at all, you can do something like this to create your output:

import json

file_content = """{"uid": 2, "user": 1}


{"uid": 2, "user": 1}


{"uid": 2, "user": 1}

"""

output = [json.loads(line)
          for line in file_content.split("\n") if line.strip() != ""]
print(output)

You can "convert" a string that contains a list to an actual list like this

>>> import ast
>>> ast.literal_eval('[{"a":1, "c":4},{"b":2, "d":5}]')
[{'a': 1, 'c': 4}, {'b': 2, 'd': 5}]

You can of course sub out the literal string for the data you read from file

json_data = [] # your list with json objects (dicts)

with open('prueba.json') as json_file:
   json_data = json.load(json_file)

for item in json_data:
    for data_item in item['data']:
        print data_item['name'], data_item['value']
