Python 安装

在linux/unix系统中，默认已经安装了Python。如下直接在命令行上执行python命令，进入Python交互式环境。

[root@master ~]# python

如果没有安装则执行：yum install python

ipython的安装

在linux/unix系统中，默认是没有安装ipython这个利器的。推荐在学习Python的时候用功能强大的ipython。在red hat 系列(centos，redhat，fedora等)安装ipython。可以直接使用yum来安装

yum install ipython

[root@master test]# yum install ipython

**********************************************************************

Welcome to IPython. I will try to create a personal configuration directory

where you can customize many aspects of IPython's functionality in:

/root/.ipython

Initializing from configuration /usr/lib/python2.4/site-packages/IPython/UserConfig

Successful installation!

Please read the sections 'Initial Configuration' and 'Quick Tips' in the

IPython manual (there are both HTML and PDF versions supplied with the

distribution) to make sure that your system environment is properly configured

to take advantage of IPython's features.

Important note: the configuration system has changed! The old system is

still in place, but its setting may be partly overridden by the settings in

"~/.ipython/ipy_user_conf.py" config file. Please take a look at the file

if some of the new settings bother you.

Please press to start IPython.
