I am trying to store the jsonas text file , I am able to print the file but am not able to store the file and also the o/p is coming wiht unicode charatcer.

PFB code.

import json
from pprint import pprint
with open('20150827_abc_json') as data_file:
    f=open("file.txt","wb")
    f.write(data=json.load(data_file))
    print (data)>f
    f.close()

When i execute it , the file gets created but its of zero byte and also how can i get rid of unicode character and also store the output.

o/p

u'Louisiana', u'city': u'New Olreans'

You simply copy the content of one file to another ? Why not just copy it ? — alpha1554

What are you expecting to happen at print (data)>f because 1) data isn't defined and 2) you are printing a greater than comparison, not f.write(data) — OneCricketeer

To serialize JSON to file you should use json.dump function. Try to use following code

import json
from pprint import pprint
with open('20150827_abc_json') as data_file, open('file.txt','w') as f:
    data=json.load(data_file)
    print data
    json.dump(data,f)

You could add f to the with statement by adding a comma

the print syntax is wrong, you put only a single > while there should be two of them >>. in python 3 (or python2 if you from __future__ import print_function) you can also write, in a more explicit way:

print("blah blah", file=yourfile)

I would also suggest to use a context manager for both files:

with open('20150827_abc_json') as data_file:
    with open("file.txt","wb") as file:
        ...

otherwise you risk that an error will leave you destination file pending.
