Question

我有以下字符串，我是从twitter streaming api收集的

"""{"created_at":"Mon Mar 11 20:15:36 +0000 2013","id":311208808837951488,"id_str":"311208808837951488","text":"ALIENS ENTRATE E' IMPORTANTE!!! \n\n\n\nMTV's Musical March Madness ritorna il 18 marzo...Siete pronti A http:\/\/t.co\/ABXEfquTJw via @Hopee_dream","source":"\u003ca href=\"http:\/\/twitter.com\/download\/android\" rel=\"nofollow\"\u003eTwitter for Android\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":1025970793,"id_str":"1025970793","name":"Tom's Perfection\u2665","screen_name":"_MyGreenEyes_","location":"","url":null,"description":"Angel,don't you cry,i'll meet you on the other side.\u2661","protected":false,"followers_count":387,"friends_count":520,"listed_count":1,"created_at":"Fri Dec 21 08:39:17 +0000 2012","favourites_count":174,"utc_offset":null,"time_zone":null,"geo_enabled":true,"verified":false,"statuses_count":772,"lang":"it","contributors_enabled":false,"is_translator":false,"profile_background_color":"C0DEED","profile_background_image_url":"http:\/\/a0.twimg.com\/images\/themes\/theme1\/bg.png","profile_background_image_url_https":"https:\/\/si0.twimg.com\/images\/themes\/theme1\/bg.png","profile_background_tile":false,"profile_image_url":"http:\/\/a0.twimg.com\/profile_images\/3363059730\/3d791e51eefa800150cd99917abc1d2c_normal.jpeg","profile_image_url_https":"https:\/\/si0.twimg.com\/profile_images\/3363059730\/3d791e51eefa800150cd99917abc1d2c_normal.jpeg","profile_banner_url":"https:\/\/si0.twimg.com\/profile_banners\/1025970793\/1362500832","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,"entities":{"hashtags":[],"urls":[{"url":"http:\/\/t.co\/ABXEfquTJw","expanded_url":"http:\/\/tl.gd\/l9f5j7","display_url":"tl.gd\/l9f5j7","indices":[101,123]}],"user_mentions":[]},"favorited":false,"retweeted":false,"possibly_sensitive":false,"filter_level":"medium"}"""

我正在进行以下操作：

import json
json_string = json_string.strip()
jsn_dict = json.loads(json_string)
print jsn_dict["text"]

给出：

ALIENS ENTRATE E' IMPORTANTE!!!

而不是：

"ALIENS ENTRATE E' IMPORTANTE!!! \n\n\n\nMTV's Musical March Madness ritorna il 18 marzo...Siete pronti A http:\/\/t.co\/ABXEfquTJw via @Hopee_dream"

在我看来，换行字符在将此字符串解析为python字典时会产生问题。

但后来我正在做json_string.strip（）操作。我以为它会从我的字符串中删除这些东西..

我做错了什么？

Answer 1

str.strip()方法仅删除字符串开头和结尾的空格字符。不是中间的任何地方。

要从字符串中删除所有换行符，您可以执行以下操作：

"some\n\n\nstring".replace("\n", "")

或

"some\n\n\nstring".translate(None, "\n")

第一个可能更容易阅读和理解。

Answer 2

我遇到了类似的问题，文字在\n符号后被截断。

在我的情况下，问题是因为我不小心将#符号添加到我用来从字典中取出值的键：

print jsn_dict['#text']

麻烦将字符串传递给json python dict
