dictionary 를 json 으로 변환

https://docs.python.org/2/library/json.html

import json

dict1 = { 'name' : 'song', 'age' : 10 }

print "dict1 = %s" % dict1
print "dict1 type = %s" % type(dict1)
print "================"

# CONVERT dictionary to json using json.dump
json_val = json.dumps(dict1)


print "json_val = %s" % json_val
print "json_val type = %s" % type(json_val)

[Python] In dictionary, converting the value from string to integer. 

Dict에서 value가 숫자형이 아닐때 숫자로 변경

Taking this below example :

'user_stats': {'Blog': '1',
                'Discussions': '2',
                'Followers': '21',
                'Following': '21',
                'Reading': '5'},

I want to convert it into:

'Blog' : 1 , 'Discussion': 2, 'Followers': 21, 'Following': 21, 'Reading': 5

>>> d = {'Blog': '1', 'Discussions': '2', 'Followers': '21', 'Following': '21', 'Reading': '5'}
>>> dict((k, int(v)) for k, v in d.iteritems())
{'Blog': 1, 'Discussions': 2, 'Followers': 21, 'Following': 21, 'Reading': 5}
