pythonMySQLdb使用教程详解-创新互联

本文主要内容python MySQLdb数据库批量插入insert，更新update的：

1.python MySQLdb的使用，写了一个基类让其他的sqldb继承这样比较方便，数据库的ip, port等信息使用json配置文件

2.常见的查找，批量插入更新

下面贴出基类代码：

# _*_ coding:utf-8 _*_
import MySQLdb
import json
import codecs
# 这个自己改一下啊
from utils.JsonUtil import get_json_from_file
def byteify(input):
  """
  the string of json typed unicode to str in python
  This function coming from stack overflow
  :param input: {u'first_name': u'Guido', u'last_name': u'jack'}
  :return:   {'first_name': 'Guido', 'last_name': 'jack'}
  """
  if isinstance(input, dict):
    return {byteify(key): byteify(value)
        for key, value in input.iteritems()}
  elif isinstance(input, list):
    return [byteify(element) for element in input]
  elif isinstance(input, unicode):
    return input.encode('utf-8')
  else:
    return input
def get_json_from_file(filename):
  with open(filename) as jf:
    jsondata = json.load(jf)
  return byteify(jsondata)
class DbBase(object):
  def __init__(self, **kwargs):
    self.db_config_file = kwargs['db_config_file']
    self.config_db(self.db_config_file)
  def config_db(self, db_config_file):
    data = get_json_from_file(db_config_file)
    host = data['host']
    user = data['user']
    pwd = data['pwd']
    db = data['db']
    port = data['port']
    self.tb_audit_mobile = data['tb_audit_mobile']
    self.conn = MySQLdb.connect(host=host, port=port, user=user, passwd=pwd, db=db, charset="utf8", use_unicode=True)
    self.cursor = self.conn.cursor()
