json.load loads from a file-like object. You either want to use json.loads:

json.loads(data)

Or just use json.load on the request, which is a file-like object:

json.load(request)

Also, if you use the requests library, you can just do:

import requests

json = requests.get(url).json()

json.dumps() is much more than just making a string out of a Python object, it would always produce a valid JSON string (assuming everything inside the object is serializable) following the Type Conversion Table.

For instance, if one of the values is None, the str() would produce an invalid JSON which cannot be loaded:

>>> data = {'jsonKey': None}
>>> str(data)
"{'jsonKey': None}"
>>> json.loads(str(data))
Traceback (most recent call last):

    obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 2 (char 1)

But the dumps() would convert None into null making a valid JSON string that can be loaded:

>>> import json
>>> data = {'jsonKey': None}
>>> json.dumps(data)
'{"jsonKey": null}'
>>> json.loads(json.dumps(data))
{u'jsonKey': None}

The json library in python has a function loads which enables you to convert a string (in JSON format) into a JSON. Following code for your reference:

import json

str1 = '{"a":"1", "b":"2"}'
data = json.loads(str1)

print(data)

Note: You have to use ' for enclosing the string, whereas " for the objects and its values.

json.loads()

import json

d = json.loads(j)
print d['glossary']['title']
