python - tweepy 流到 sqlite 数据库 - 语法无效

Question

下面的代码正在为一个变量流式传输 Twitter 公共(public)时间线，该变量将任何推文输出到控制台。我想将相同的变量(status.text、status.author.screen_name、status.created_at、status.source)保存到 sqlite 数据库中。当我的脚本看到一条推文但没有任何内容写入 sqlite 数据库时，我收到语法错误。

错误:

$ python stream-v5.py @lunchboxhq

您在以下代码的最后一行(您发布的第 34-37 行)缺少右括号:

            cur.executemany("INSERT INTO TWEETS(?, ?, ?)", (status.text, 
                                                        status.author.screen_name, 
                                                        status.created_at, 
                                                        status.source)

只需在您的元组参数后添加一个括号即可立即关闭方法调用。
