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
