Python报告"ValueError:无法解码JSON对象"

尝试将对象提取到特定元素时,我收到此错误消息

Traceback (most recent call last):
  File "twitter_mining.py", line 17, in 
    tweets_data = json.loads(tweets_data_path)
  File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 339, in loads

ValueError: No JSON object could be decoded

我的代码

tweets_data_path = 'data.txt'
tweets_data = json.loads(tweets_data_path)
tweets = pd.DataFrame()
tweets['text'] = map(lambda tweet: tweet['text'], tweets_data)

数据 - http://intellij.my/rnd/nlp/sentiment-analysis/data.txt

json.loads 不接受文件名作为参数.

阅读文件的内容并将其传递给loads.

tweets_data_path = 'data.txt'
with open(tweets_data_path) as file:
    tweets_data = json.loads(file.read())

或者使用load.

tweets_data_path = 'data.txt'
with open(tweets_data_path) as file:
    tweets_data = json.load(file)
