python - How to get data from Object Oriented Programming to mySQL? -

how can pass data object oriented programming mysql in python? need make connection in every class?

update:

this object orinted

class attentiondatapoint(datapoint):     def __init__ (self, _datavaluebytes):         datapoint._init_(self, _datavaluebytes)         self.attentionvalue=self._datavaluebytes[0]      def __str__(self):         if(self.attentionvalue):             return "attention level: " + str(self.attentionvalue)  class meditationdatapoint(datapoint):     def __init__ (self, _datavaluebytes):         datapoint._init_(self, _datavaluebytes)         self.meditationvalue=self._datavaluebytes[0]      def __str__(self):         if(self.meditationvalue):             return "meditation level: " + str(self.meditationvalue) 

and try data mysql using coding.

import time import smtplib import datetime import mysqldb  db = mysqldb.connect("192.168.0.101", "fyp", "123456", "system") cur = db.cursor()  while true:     meditation_level = meditationvalue()     attention_level = attentionvalue()     current_time = datetime.datetime.now()      sql = "insert table (id, meditation_level, attention_level, current_time) values ('test1', %s, %s, %s)"     data = (meditation_level, attention_level, current_time)     cur.execute(sql, data) db.commit()  db.close() 

update:

datapoint

class datapoint: def __init__(self, datavaluebytes): self._datavaluebytes = datavaluebytes 

i thinking of class has function connection , pass instance of class every class need connection (here db instance), or may not! it's idea used in other languages.
