Linux

Python 2.3 on Debian

from module import * in Python is like use module in Perl; import module in Python is like require module in Perl.
from module import * in Python is like import module.* in Java; import module in Python is like import module in Java.

Debian 3.1 安装后自带 Python 2.3.5
>>> import sys
>>> sys.path.append('/home/allen/test/diveintopython-5.4/py') // apihelper.py 在 py 目录下
>>> import apihelper
>>> sys.path

Python 2.4 on Debian

#apt-get install python2.4

设置环境 

export PYTHONPATH = /usr/lib/python2.4 
or
wget http://download.huihoo.com/python/2.4.3/Python-2.4.3.tgz
tar zxvf Python-2.4.3.tgz
cd Python-2.4.3
./configure 
make
make install // installed to /usr/local/lib/python2.4
/usr/local/bin/python2.4
Python 2.4.3 (#1, Mar  5 2007, 15:20:37)
[GCC 3.3.5 (Debian 1:3.3.5-13)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>
ln -s /usr/local/bin/python2.4 /usr/bin/python

设置环境, 共存多个python版本, Default python version in Debian

Python 2.5 on Debian

wget http://www.python.org/ftp/python/2.5/Python-2.5.tgz
tar zxvf Python-2.5.tgz
cd Python-2.5
./configure 
make
make install

设置环境 

export PYTHONPATH =

Solaris

FreeBSD

FreeBSD 6.1 安装有 Python 2.4.2

Windows

http://download.huihoo.com/python/2.5/python-2.5.msi
set path=%path%;C:\Python25
set lib=%lib%;C:\Python25\lib

运行命令行或集成开发环境 IDLE 

>>> help()
help>modules 
help>sys
help>modules search 
help>SearchEngine
help>modules hash
help>hashlib
help>quit
>>>

获得 mod_python , http://www.apache.org/dist/httpd/modpython/win/ 

http://www.apache.org/dist/httpd/modpython/win/3.3.0b/mod_python-3.3.0b.win32-py2.5-Apache2.2.exe
会被安装到 C:\Python25\Lib\site-packages\ 
并在安装过程中提示输入 Apache 的位置， C:\apache-2.2.3
mod_python.so 被添加到 C:\apache-2.2.3\modules

修改 httpd.conf 

LoadModule python_module modules/mod_python.so
<Directory "C:/myweb">
  SetHandler mod_python
  PythonHandler mod_python.publisher
</Directory>

创建index.py文件 

def index(name):
  return "Welcome %s" % name   
http://localhost/python/?name=huihoo (OK :)

下载 mod_python example

MySQL

http://sourceforge.net/projects/mysql-python/ 

获得 MySQL-python.exe-1.2.1_p2.win32-py2.4.exe 
包安装到 C:\Python24\Lib\site-packages\MySQLdb

or Debian 

#apt-get install python2.3-mysqldb
>>> import MySQLdb
>>> db = MySQLdb.connect("localhost","root","password","mysql")
>>> cursor = db.cursor()
>>> sql = "select * from db"
>>> cursor.execute(sql)
>>> data = cursor.fetchone()
>>> print data
>>> db.close()
