我正在做一个类似于情感分析的研究项目。我使用Tweepy从twitter中提取了推文。 我得到的数据是这样的:如何只从Tweepy中提取的推文中获取文本部分?

{"created_at":"Sat Apr 22 07:28:47 +0000 2017","id":855684794939842560,"id_str":"855684794939842560","text":"#PL | FIXTURES - 22 April 2017 \nWest Ham v Everton 16:00\nHull v Watford\nSwansea v Stoke \nBournemouth v Middlesbrough #CCFMSport","source":"\u003ca href=\"http:\/\/twitter.com\" rel=\"nofollow\"\u003eTwitter Web Client\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":256051042,"id_str":"256051042","name":"Ayanda Frances Felem","screen_name":"AyandaFelemZA","location":"Cape Town, South Africa","url":"http:\/\/ccfm.org.za","description":"Sports Producer\/Reporter for @RadioCCFm, Views are my own.

现在我想提取只能从该文件中鸣叫“文本”。我曾经尝试这样做:

import json 

tweets_data_path = 'twitter_streaming.txt' 
tweets_data = [] 
tweets_file = open(tweets_data_path, "r") 

json_load = json.load(tweets_file) 
texts = json_load['text'] 
coded = texts.encode('utf-8') 
s = str(coded) 
tweets_data.append(s[1:-2)) 
print tweets_data 

但我得到一个错误说:

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

试图寻找此错误的原因,但没有发现任何具体。

我在做什么错?有没有更好的办法?

print a["text"] 

我只是使用这一行代码,它返回给我以下输出。

#PL | FIXTURES - 22 April 2017 
West Ham v Everton 16:00 
Hull v Watford 
Swansea v Stoke 
Bournemouth v Middlesbrough #CCFMSport 

虽然问题不明确,您是否正在寻找此文本?
