Parse This Custom Twitter Capture Data With Python and Create Statistics

I'm trying to gather Twitter statistics from a specific dataset that was provided to me. I have no control over how the data is formatted before it is given to me so I'm locked into this messy for.

I would like some suggestions on how I can build a python program to parse this sort of input and outputting something more along the lines of a CSV file with the field titles as header and the values below.

I want to use python because eventually I would like to use some statistical tools that I've already put together.

Additionally the output of a CSV type format is preferred because I may input it into something like SPSS for statistical verification.

Here's a sample of what a single post looks like from the dataset:

{"text":"A gente todos os dias arruma os cabelos: por que não o coração?","contributors":null,"geo":null,"retweeted":false,"in_reply_to_screen_name":null,"truncated":false,"entities":{"urls":[],"hashtags":[],"user_mentions":[]},"in_reply_to_status_id_str":null,"id":50270714498002945,"source":"web","in_reply_to_user_id_str":null,"favorited":false,"in_reply_to_status_id":null,"created_at":"Tue Mar 22 19:00:46 +0000 2011","in_reply_to_user_id":null,"retweet_count":0,"id_str":"50270714498002945","place":null,"user":{"location":"Brasil, Recife-PE","statuses_count":16,"profile_background_tile":true,"lang":"en","profile_link_color":"867c5f","id":59154474,"following":null,"favourites_count":0,"protected":false,"profile_text_color":"91957f","verified":false,"contributors_enabled":false,"description":"","profile_sidebar_border_color":"eae2bc","name":"Natalia Aráujo","profile_background_color":"eae2bc","created_at":"Wed Jul 22 15:27:15 +0000 2009","followers_count":10,"geo_enabled":false,"profile_background_image_url":"http://a3.twimg.com/profile_background_images/220796682/music-2.png","follow_request_sent":null,"url":null,"utc_offset":-10800,"time_zone":"Brasilia","notifications":null,"profile_use_background_image":true,"friends_count":18,"profile_sidebar_fill_color":"eae2bc","screen_name":"nat_araujo","id_str":"59154474","show_all_inline_media":false,"profile_image_url":"http://a0.twimg.com/profile_images/1247378890/154254_normal.JPG","listed_count":1,"is_translator":false},"coordinates":null}

The dataset is one continuous line with NO line returns between posts. The only delimiter between the actual posts is:

All posts start with

{"text":

and end with

null}

of course would be glad to share my results with everyone.

Based on what everyone is saying I've started off with the following:

import sys
import json
from pprint import pprint

if len(sys.argv) != 2:
    print 'To Use: twitterjson2cvs.py (path/filename)'
    sys.exit()

inputfile = open(sys.argv[1])

jsondatain = json.load(inputfile)
pprint(jsondatain)

inputfile.close()

which outputs something a bit cleaner in the form of:

I've added to the previous code in an attempt to output to a CSV file:

import sys
import json
#from pprint import pprint
import csv

if len(sys.argv) != 2:
    print 'To Use: twitterjson2cvs.py (path/filename)'
    sys.exit()

inputfile = open(sys.argv[1])

jsondatain = json.load(inputfile)

f=csv.writer(open("test.csv","wb+"))

f.writerow(["contributors","coordinates","created_at","entities","hashtags","urls","user_mentions","favorited","geo","id","id_str","in_reply_to_screen_name","in_reply_to_status_id","in_reply_to_status_id_str","in_reply_to_user_id","in_reply_to_user_id_str","place","retweet_count","retweeted","source","text","truncated","user","contributors_enabled","created_at","description","favourites_count","follow_request_sent","followers_count","following","friends_count","geo_enabled","id","id_str","is_translator","lang","listed_count","location","name","notifications","profile_background_color","profile_background_image_url","profile_background_tile","profile_image_url","profile_link_color","profile_sidebar_border_color","profile_sidebar_fill_color","profile_text_color","profile_use_background_image","protected","screen_name","show_all_inline_media","statuses_count","time_zone","url","utc_offset","verified"])
for x in jsondatain:
    f.writerow([x["contributors"],x["fields"]["coordinates"],x["fields"]["created_at"],x["fields"]["entities"],x["fields"]["hashtags"],x["fields"]["urls"],x["fields"]["user_mentions"],x["fields"]["favorited"],x["fields"]["geo"],x["fields"]["id"],x["fields"]["id_str"],x["fields"]["in_reply_to_screen_name"],x["fields"]["in_reply_to_status_id"],x["fields"]["in_reply_to_status_id_str"],x["fields"]["in_reply_to_user_id"],x["fields"]["in_reply_to_user_id_str"],x["fields"]["place"],x["fields"]["retweet_count"],x["fields"]["retweeted"],x["fields"]["source"],x["fields"]["text"],x["fields"]["truncated"],x["fields"]["user"],x["fields"]["contributors_enabled"],x["fields"]["created_at"],x["fields"]["description"],x["fields"]["favourites_count"],x["fields"]["follow_request_sent"],x["fields"]["followers_count"],x["fields"]["following"],x["fields"]["friends_count"],x["fields"]["geo_enabled"],x["fields"]["id"],x["fields"]["id_str"],x["fields"]["is_translator"],x["fields"]["lang"],x["fields"]["listed_count"],x["fields"]["location"],x["fields"]["name"],x["fields"]["notifications"],x["fields"]["profile_background_color"],x["fields"]["profile_background_image_url"],x["fields"]["profile_background_tile"],x["fields"]["profile_image_url"],x["fields"]["profile_link_color"],x["fields"]["profile_sidebar_border_color"],x["fields"]["profile_sidebar_fill_color"],x["fields"]["profile_text_color"],x["fields"]["profile_use_background_image"],x["fields"]["protected"],x["fields"]["screen_name"],x["fields"]["show_all_inline_media"],x["fields"]["statuses_count"],x["fields"]["time_zone"],x["fields"]["url"],x["fields"]["utc_offset"],x["fields"]["verified"]])

#pprint(jsondatain)

inputfile.close()

However when I run it I get:

  File "twitterjson2cvs.py", line 28, in <module>
    f.writerow([x["contributors"],x["fields"]["coordinates"],x["fields"]["created_at"],x["fields"]["entities"],x["fields"]["hashtags"],x["fields"]["urls"],x["fields"]["user_mentions"],x["fields"]["favorited"],x["fields"]["geo"],x["fields"]["id"],x["fields"]["id_str"],x["fields"]["in_reply_to_screen_name"],x["fields"]["in_reply_to_status_id"],x["fields"]["in_reply_to_status_id_str"],x["fields"]["in_reply_to_user_id"],x["fields"]["in_reply_to_user_id_str"],x["fields"]["place"],x["fields"]["retweet_count"],x["fields"]["retweeted"],x["fields"]["source"],x["fields"]["text"],x["fields"]["truncated"],x["fields"]["user"],x["fields"]["contributors_enabled"],x["fields"]["created_at"],x["fields"]["description"],x["fields"]["favourites_count"],x["fields"]["follow_request_sent"],x["fields"]["followers_count"],x["fields"]["following"],x["fields"]["friends_count"],x["fields"]["geo_enabled"],x["fields"]["id"],x["fields"]["id_str"],x["fields"]["is_translator"],x["fields"]["lang"],x["fields"]["listed_count"],x["fields"]["location"],x["fields"]["name"],x["fields"]["notifications"],x["fields"]["profile_background_color"],x["fields"]["profile_background_image_url"],x["fields"]["profile_background_tile"],x["fields"]["profile_image_url"],x["fields"]["profile_link_color"],x["fields"]["profile_sidebar_border_color"],x["fields"]["profile_sidebar_fill_color"],x["fields"]["profile_text_color"],x["fields"]["profile_use_background_image"],x["fields"]["protected"],x["fields"]["screen_name"],x["fields"]["show_all_inline_media"],x["fields"]["statuses_count"],x["fields"]["time_zone"],x["fields"]["url"],x["fields"]["utc_offset"],x["fields"]["verified"]])
TypeError: string indices must be integers

The error has something to do with how the formatting of the fields but I'm not seeing it.

I updated the code to reflect your format suggestion as follows:

import sys
import json
import csv

if len(sys.argv) != 2:
    print 'To Use: twitterjson2cvs.py (path/filename)'
    sys.exit()

Everything is working great up to this point now for a single JSON formatted input file. The previous example JSON string input into this program:

Now the only problem is that my I have input files that have multiple JSON strings inline with each other all on one continuous line. When I attempt to run the same program on those files I get the following error:

Traceback (most recent call last):
  File "workspace/coalmine-datafilter/src/twitterjson2cvs.py", line 22, in <module>
    jsonindata = json.load(inputfile)
  File "/usr/lib/python2.6/json/__init__.py", line 267, in load

    raise ValueError(errmsg("Extra data", s, end, len(s)))
ValueError: Extra data: line 1 column 1514 - line 2 column 1 (char 1514 - 2427042)

The input file is very large, (ie: multiple thous开发者_JAVA百科ands of Twitter posts), I don't know if the error is due to the number of posts or if it's because the file has multiple {"...."}{"...."} all on the same line. Do I perhaps need to add a line return somehow after each feed?

this should get you started...you will need to take care of the nested objects

import json
import csv
f = file('test.json', 'r')
data = json.load(f)
#result = []
for k,v in data.iteritems():
    print k,v
    #result.append(v)
f = file('output.csv', 'w')
writer = csv.writer(f)
writer.writerows(result)

The input here is JSON. Python has a JSON module. Happily it has a CSV module too. So that's your input and output taken care of!

Update

You are getting there!

Your call to writerow() needs to look more like (not in a for-loop):

f.writerow( 
        (
            jsonindata['contributors'],
            jsonindata['coordinates'],
            jsonindata['created_at'],
            jsonindata['entities']['hashtags'],
            jsonindata['entities']['urls'],
            jsonindata['entities']['user_mentions'],
            jsonindata['favorited'],
            jsonindata['geo'],
            jsonindata['id'],
            jsonindata['id_str'],
            jsonindata['in_reply_to_screen_name'],
