paip.python连接mysql最佳实践o4
python连接mysql 还使用了不少时间...,相比php困难多了..麻烦的.. 而php,就容易的多兰..
python标准库没mysql库,只好第三方兰..
先看累挂..说MySQLdb...三,不行..
1. MySQLdb( MySQL-python 1.2.3)支持派森python 2.7的直接windows安装包，用的python 2.7的朋友可以使用，使用python 3.x的朋友就不支持了
2.还没二进制的安装包,..要源码编译..麻烦的..windows上要安装linux编译环境MinGW了..pass..

================mysql-connector-python
目前MySQLdb并不支持python3.x，网上找了一些方法，后来我还是偶然发现MySQL官方已经提供了MySQL连接器，而且已经有支持Python3.x的版本了。MySQL Connector/Python, a self-contained Python driver for communicating with MySQL servers. 这个用起来还是感觉比较顺手的。有二进制包了...
mysql-connector-python-1.1.6-py3.3.msi (111kb)
三,安装的时候儿要python了.俄的机器上有个python3.3.4了,绿色版本的..因为这个新不上...只好在安装了python3.3.5(20M),这才安上.安装到个D:Python335Libsite-packagesmysql 里面兰..看累挂,都是py文件,没编译..
eric5里面f2 运行文件 D:Python335Python.exe D:workSpacePythonhalo.py ,三,说新不上mysql 模块..查看sys.path这个库加载的路线..
import sys, os
print( sys.path)
三是eric的路线
['', 'D:\workSpacePython', 'D:\Python334eric\Lib\site-packages\eric5\DebugClients\Python3', 'D:\Python334eric\python33.zip', 'D:\Python334eric\DLLs', 'D:\Python334eric\lib', 'D:\Python334eric', 'D:\Python334eric\lib\site-packages', 'D:\Python334eric\lib\site-packages\win32',
'D:\Python334eric\lib\site-packages\win32\lib', 'D:\Python334eric\lib\site-packages\Pythonwin']
只好不个那复制到个仄哈面儿,ok兰...
Python.exe D:workSpacePythongetpath.py
===============例子代码
my_dict = { 'a':1, 'b':2 }
#然后敲"my_dict."，出不来字典的各个函数，ctrl+space也不行。
