我有一组推文已经保存到了一个 .txt 文件中。
我想要在 Python 中将某些属性放入 SQLite 表格中。我成功地创建了这个表格。
import pandas
import sqlite3
conn = sqlite3.connect('twitter.db')
c = conn.cursor()
c.execute(CREATE TABLE Tweet
(
created_at VARCHAR2(25),
id VARCHAR2(25),
text VARCHAR2(25)
source VARCHAR2(25),
in-reply_to_user_ID VARCHAR2(25),
retweet_Count VARCHAR2(25)
)
在尝试将解析的数据添加到数据库之前,我试图创建一个数据框来查看它。
tweets =pandas.read_table('file.txt', sep=',')
I get the error:
CParserError: Error tokenizing data. C error: Expected 63 fields in line 3, saw 69
我猜测在这些字段中,不仅有逗号分隔,字符串内部也有逗号。
此外,Twitter数据的格式我之前没有接触过。每个字段都以括号中的变量名开始,后跟冒号和用更多括号分隔的数据。例如:
"created_at":"Fri Oct 11 00:00:03 +0000 2013",
那么我该如何将这个内容转换成标准的表格格式,其中变量名在顶部呢?
一个完整的推文示例如下:
