安装好python环境后，通过执行/usr/local/python/bin/python2.7可以直接进入python环境，进行相关的编辑：
[root@agent ~]# /usr/local/python/bin/python2.7 Python 2.7.10 (default, Jul 10 2015, 15:41:26) [GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> 100 + 200 300 >>> print "hello,world" hello,world
但是，此时，新建一个列表list1,如果想查看其相关的属性，使用Tab键没有任何反应
>>> list1=['a','b',1,3] >>> list1.
已经习惯了使用linux Tab来补全命令，在python里面却不能使用Tab，这种感觉真不爽，从网上搜了一下，如何使用python tab自动补全的脚本
1.进入用户的宿主目录（家目录），创建一个名为.startup文件，具体内容如下：
import sys
import readline
import rlcompleter
import atexit
import os
readline.parse_and_bind('tab: complete')
histfile = os.path.join(os.environ['HOME'], '.pythonhistory')
try:
readline.read_history_file(histfile)
except IOError:
pass
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter 2.在/root目录的.bashrc文件添加环境变量,执行以下命令即可：
echo "export PYTHONSTARTUP=~/.pythonstartup" >> ~/.bashrc
3.退出SSH重新登陆即，进入python后即可用tab补全
