Python JSON: NameError: Tên 'false' không được định nghĩa

Question

Tôi đã cố gắng để json.load dict này từ twitter:

tôi đã làm json.load() để dict đó. nhưng tôi đã dẫn đến thông báo lỗi bên dưới:

NameError: name 'false' is not defined 

Điều gì đã xảy ra?

Answer 1

Bạn đang cố dán chuỗi thẳng vào Python. Đừng làm vậy, đó là chuỗi chuỗi đại diện cho các đối tượng.

JSON chỉ trông rất giống Python, nhưng nó không phải là mã Python thực tế.

Ở đây tôi nạp này như là một chuỗi Python liệu không giải thích bất kỳ thoát trong đó:

>>> import json 
>>> json_string = r'''{"created_at":"Thu Jul 10 20:02:00 +0000 2014","id":487325888950710272,"id_str":"487325888950710272","text":"\u5f81\u9678\u300c\u5de6\u8155\u306e\u7fa9\u624b\u306f\u30db\u30ed\u3060\u300d","source":"\u003ca href=\"http:\/\/twittbot.net\/\" rel=\"nofollow\"\u003etwittbot.net\u003c\/a\u003e","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":"\u3053\u3093\u306a\uff30\uff30\u306f\u5acc\u3060\u3002","screen_name":"iyada_pp","location":"\u516c\u5b89\u5c40\u306e\u3069\u3053\u304b\u3002","url":null,"description":"\u3010\u3053\u3093\u306aPSYCHO-PASS\u306f\u5acc\u3060\u306a\u3011\u3068\u3044\u3046\u304f\u3060\u3089\u306a\u3044\u5984\u60f3bot\u3067\u3059\u3002\u30ad\u30e3\u30e9\u5d29\u58ca\u304c\u6fc0\u3057\u3044\u306e\u3067\u3054\u6ce8\u610f\u304f\u3060\u3055\u3044\u3002","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"}'''

Answer 2

twitter dòng cung cấp cho bạn một chuỗi Unicode chữ. bạn có thể kiểm tra tương tự bằng cách sử dụng

type(data) 

Bạn cần giải mã dữ liệu vào UTF-8 trước khi sử dụng chức năng deserialization JSON ví dụ.

json.loads(data.decode('utf-8')) 

và sau đó sử dụng từ điển để xử lý luồng. Chúc may mắn

Answer 3

Python phân biệt chữ hoa chữ thường.

False != false
