Question

下面的代码在使用MySQLDB的python2中完美运行，我怎样才能使它与Python3兼容？

我已经调试并搜索了类似的问题。

错误：在以下情况中忽略了例外：＆gt;回溯（最近一次呼叫最后）：文件＆gt; ＆GT; ＆GT; ＆＃34; /usr/local/lib/python3.4/dist-packages/pymysql/cursors.py" ;,第41行，在del文件中＆gt; ＆＃34; /usr/local/lib/python3.4/dist-packages/pymysql/cursors.py"，第47行，关闭ReferenceError：弱引用的对象不再存在 -

class Database():

    def __init__(self):
        self.host = 'localhost'
        self.user = 'user'
        self.password = 'pwd'  
        self.db = 'dbname'
        self.connection = pymysql.connect(host=self.host, user=self.user, passwd=self.password, db=self.db,use_unicode=True, charset="utf8")
        self.cursor = self.connection.cursor()

    def storeToDB(self,ID,string,g,e):
        import datetime

        curr_time = datetime.datetime.now()
        status = 0
        try:
            self.cursor.execute("""INSERT INTO master_data (`job_id`,`sstring`,`grl`,`erl`,`status`,`insert_timestamp`) \
            VALUES (%s,%s,%s,%s,%s,%s)""",(jobID,search_string,g,e,status,curr_time))
            self.connection.commit()
        except:
            self.connection.rollback()
if __name__ == "__main__":
    db = Database()
    db.storeToDB(20,"hello","something.com","e.com")

尝试在db操作完成之前做一些选择：

cursor.close()
connection.close()
