我正在尝试编写一个程序，使用他们的Stream API和Tweepy从Twitter传输推文。这是我的代码的相关部分：
def on_data(self, data):
if data.user.id == "25073877" or data.in_reply_to_user_id == "25073877":
self.filename = trump.csv
elif data.user.id == "30354991" or data.in_reply_to_user_id == "30354991":
self.filename = harris.csv
if not 'RT @' in data.text:
csvFile = open(self.filename, 'a')
csvWriter = csv.write(csvFile)
print(data.text)
try:
csvWriter.writerow([data.text, data.created_at, data.user.id, data.user.screen_name, data.in_reply_to_status_id])
except:
pass
def on_error(self, status_code):
if status_code == 420:
return False
代码应该做的是流式传输推文并编写推文的文本，创建日期，高音扬声器的用户ID，他们的屏幕名称，以及如果推文是一个他们回复的状态的回复ID答复。但是，我收到以下错误：
File "test.py", line 13, in on_data
if data.user.id == "25073877" or data.in_reply_to_user_id == "25073877":
AttributeError: 'unicode' object has no attribute 'user'
有人可以帮帮我吗？谢谢！
编辑：正在读入“数据”的样本

所以我认为修改后的问题是如何告诉程序只将这个JSON输出的部分写入CSV文件？我一直在使用Twitter的流API提供“数据”属性的引用。
如您的评论中所述，推文数据采用“JSON格式”。我相信你的意思是它是一个JSON格式的字符串（unicode），而不是一个解析过的JSON对象。要在代码中访问您想要的字段，您需要使用json解析数据字符串。
EG
import json
json_data_object = json.loads(data)
然后，您可以像访问字典一样访问字段，例如
json_data_object['some_key']['some_other_key']
