如何在每行末尾添加\\ n

Question

Below is my code:

import requests

html = requests.get(

html_str = html.content
Html_file= open("fb_remodel.txt",'w')
Html_file.write(html_str)
Html_file.close()

This produces a text file which

{"data":[{"id":"359434924192565_361115077357883","created_time":"2013-11-05T18:52:24+0000"},{"id":"116929191671920_664658976898936","created_time":"2013-11-05T18:51:57+0000"},

I want there to be a newline right after every }, .

Answer 1

You can "pretty print" JSON with Python's "json" module

See: http://docs.python.org/2/library/json.html

Pretty printing:

import json
print json.dumps({'4': 5, '6': 7}, sort_keys=True,
...                  indent=4, separators=(',', ': '))
{
    "4": 5,
    "6": 7
}

Answer 2

You are receiving a JSON value without any newlines; you'll have to manually insert newlines yourself:

response = requests.get(...)
json_str = response.content
json_str = json_str.replace('},', '},\n')
with open('fb_remodel.txt', 'w') as json_file:
    json.file.write(json_str)

I replaced 'html' with 'json' in your code and improved the file handling a little (in the above code the with statement auto-closes the file object for you).

The code uses string replacement to replace all }, strings with },\\n , effectively adding in extra newlines the original response did not have.

Answer 3

Use the JSON module to pretty print:

import json
json_pp = json.dumps(html_str, sort_keys=True,
              indent=4, separators=(',', ': '))

Html_file= open("fb_remodel.txt",'w')
Html_file.write(json_pp)
Html_file.close()

I would also use:

html_str = html.text

As you may know, requests will decode the response to Unicode using the correct character set.
