python 将数据写入SQLITE3数据库

利用了创建列表和查询两种方式，

１：创建列表的时候　用了一个异常的判断：

２：通过python插入数据到json ：

方法１：

temp=\[time , agv\_id , obstacle,obstacle\_name\]

cursor.execute("insert into exception (time,AGV\_ID,Error\_ID,infomation) values (?,?,?,?)", temp)

方法２：

cursor.execute("insert into exception values('%s', '%s','%s' ) " %(start\_time ,ID ,infomation))  
  个人感受，方法１　比方法２　要好
