>>> import sys #導入sys模塊 >>> sys.path #查看python環境變量 ['', '/usr/lib64/python27.zip', '/usr/lib64/python2.7', '/usr/lib64/python2.7/plat-linux2', '/usr/lib64/python2.7/lib-tk', '/usr/lib64/python2.7/lib-old', '/usr/lib64/python2.7/lib-dynload', '/usr/lib64/python2.7/site-packages', '/usr/lib64/python2.7/site-packages/gtk-2.0', '/usr/lib/python2.7/site-packages']
環境變量中 搜索順序 ‘’ 代表當前目錄，會按照這個順序來搜索你要的模塊。
我的放在 /usr/lib64/python2.7/site-packages/ 這個目錄
在指定的目錄下面添加 tab.py (tab.py 是借的別人的)
/usr/lib64/python2.7/site-packages $sudo vim tab.py
#!/bin/env python
import sys
import readline
import rlcompleter
import atexit
import os
# tab completion
readline.parse_and_bind('tab: complete')
# history file
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導入tab模塊
>>> import tab >>> import os >>> os. #已經支持tab功能了 Display all 249 possibilities?

可以調用shell命令
>>> os.system('ip r')
