My apologies for what is probably a simple question to most on this group. However, I am new to python and very new to json.
I am trying to read in a json file from a twitter download. There are, generally, two types of lines: those lines with "text" and the other lines. I am only interested in the lines with "text". I am also only interested in lines with "lang":"en", but I haven't gotten far enough to implement that condition in the code snippets below. I have gotten Option 2 below to sort of work. It works fine for 'text', but doesn't work for 'lang'. FWIW I am using Python 2.6.4 Can someone tell me what I'm doing wrong with the following code snippets and/or point me toward an example of an implementation? Many thanks for your patience. --------------------------------- import sys import json f = open(sys.argv[1]) #option 1 for line in f: j = json.loads(line) try: 'text' in j print "TEXT: ", j except: print "EXCEPTION: ", j continue else: text=j['text'] ----snip -------- #option 2 does basically the same thing as option 1 , but also looks for 'lang' for line in f: j = json.loads(line) if 'text' in j: if 'lang' in j: lang = j['lang'] print "language", lang text = j['text'] ----snip -------- ------ Two Sample Twitter lines ------------- {"text":"tech managers what size for your teams? better to have 10-20 ppl per manager or 2-5 and have the managers be more hands on?","in_reply_to_user_id":null,"coordinates":null,"geo":null,"created_at":"Thu Apr 22 17:35:42 +0000 2010","contributors":null,"source":"<a href= \"http://twitterfeed.com\" rel=\"nofollow\">twitterfeed</ a>","in_reply_to_status_id":null,"place":null,"truncated":false,"in_reply_to_screen_name":null,"user": {"favourites_count": 0,"profile_text_color":"000000","time_zone":"Eastern Time (US & Canada)","created_at":"Tue Oct 27 19:50:51 +0000 2009","statuses_count": 286,"notifications":null,"profile_link_color":"0000ff","description":"I write code and talk to people.
