Part of the code to insert data:

            try:
                sql = "INSERT INTO {}({}) VALUES(%s)".format(table,cols) % q[0]
                print sql           
                result = self.cur.executemany(sql,q)
                #result = self.cur.execute(sql)
                insert_id = self.db.insert_id()
                self.db.commit()
                #判断是否执行成功
                if result:
                    return insert_id
                else:
                    return 0
            except MySQLdb.Error,e:
                #发生错误时回滚
                print "数据库错误，原因%d: %s" % (e.args[0], e.args[1])               
                self.db.rollback()

After executing the program, we get

INSERT INTO zydc(follow, house_url, price_area, houseinfo) VALUES(%s)
数据库错误，原因1136: Column count doesn't match value count at row 1

There was no problem when I entered the insert statement manually in the database, but I don’t know why the execute error occurred.
When I insert data into a table that only stores links, there is no problem at all.
Just now when I wanted to output the cause of the error, I found that the data was inserted successfully. Then I tried to use executemany() and another error occurred.
