Python解析一段json字符串，直接调用json.loads报错：
NameError: name 'false' is not defined
解决方案：
用Python的r 原始字符串(raw strings)，即在json字符串之前加入r'''，之后加入'''。例如：
>>> import json
>>> json_string = r'''{"created_at":"Thu Jul 10 20:02:00 +0000 2014","id":487325888950710272,"id_str":"487325888950710272","text":"u5f81u9678u300cu5de6u8155u306eu7fa9u624bu306fu30dbu30edu3060u300d","source":"u003ca href="http://twittbot.net/" rel="nofollow"u003etwittbot.netu003c/au003e","truncated":false,"in_reply_to_status_id":null,"in_reply_to_status_id_str":null,"in_reply_to_user_id":null,"in_reply_to_user_id_str":null,"in_reply_to_screen_name":null,"user":{"id":1429838018,"id_str":"1429838018","name":"u3053u3093u306auff30uff30u306fu5accu3060u3002","screen_name":"iyada_pp","location":"u516cu5b89u5c40u306eu3069u3053u304bu3002","url":null,"description":"u3010u3053u3093u306aPSYCHO-PASSu306fu5accu3060u306au3011u3068u3044u3046u304fu3060u3089u306au3044u5984u60f3botu3067u3059u3002u30adu30e3u30e9u5d29u58cau304cu6fc0u3057u3044u306eu3067u3054u6ce8u610fu304fu3060u3055u3044u3002","protected":false,"followers_count":99,"friends_count":98,"listed_count":5,"created_at":"Wed May 15 07:52:33 +0000 2013","favourites_count":0,"utc_offset":null,"time_zone":null,"geo_enabled":false,"verified":false,"statuses_count":12584,"lang":"ja","contributors_enabled":false,"is_translator":false,"is_translation_enabled":false,"profile_background_color":"C0DEED","profile_background_image_url":"http://abs.twimg.com/images/themes/theme1/bg.png","profile_background_image_url_https":"https://abs.twimg.com/images/themes/theme1/bg.png","profile_background_tile":false,"profile_image_url":"http://pbs.twimg.com/profile_images/3661872276/ab7201283dac5dc1789bb6dfa9b6abe4_normal.jpeg","profile_image_url_https":"https://pbs.twimg.com/profile_images/3661872276/ab7201283dac5dc1789bb6dfa9b6abe4_normal.jpeg","profile_link_color":"0084B4","profile_sidebar_border_color":"C0DEED","profile_sidebar_fill_color":"DDEEF6","profile_text_color":"333333","profile_use_background_image":true,"default_profile":true,"default_profile_image":false,"following":null,"follow_request_sent":null,"notifications":null},"geo":null,"coordinates":null,"place":null,"contributors":null,"retweet_count":0,"favorite_count":0,"entities":{"hashtags":[],"symbols":[],"urls":[],"user_mentions":[]},"favorited":false,"retweeted":false,"filter_level":"medium","lang":"ja"}'''
