參考文件：

環境 windows10 | python3.3 

方法如下：>下載安裝的指令碼https://bootstrap.pypa.io/ez_setup.py，下載該指令碼後執行      >python ez_setup.py      >即可。指令碼會自動判斷python的版本，自動下載，安裝。 2.安裝pip 方法如下：我們同樣需要在Python的官網上去下載， 解壓到某目錄下,cd進去，使用命令 python setup.py install 進行安裝 將X:\Python\Script 目錄新增到path   3.安裝mysqldb pip install mysql-python 測試檔案： DB.py

使用測試：

use.py

#!/usr/bin/env python
from DB import ZDB
def main():
    dbconfig={'host':' ',
              'port':3306,
              'user':' ',
              'passwd':' ',
              'db':'test',
              'charset':'UTF8'}
    db=ZDB(dbconfig)

    sql = "SELECT * FROM `user`"
    db.query(sql)
    result = db.fetchAllRows()
    print "This is the result>",result
    for row in result:
        for colum in row:
            print colum
    db.close()
main()

使用命令 python use.py 進行呼叫 _____________________________________________________________ 也可以使用pymysql查詢 簡單demo如下所示：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import pymysql
conn=pymysql.connect(host='localhost',
                     port=3306,
                     user='root',
                     passwd='root',
                     db='test',
                     charset='utf8')
cur = conn.cursor()
sql = "SELECT * FROM chart_pie"
cur.execute(sql)
for r in cur.fetchall():
    for column in r:
        print(r)

conn.close()
