Python 2.7.8 (default, Nov 10 2014, 08:19:18)

>>> import sys                               #匯入sys模組>>> sys.path                                 #查看python環境變數[‘‘, ‘/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‘]

環境變數中 搜尋順序 ‘’ 代表目前的目錄，會按照這個順序來搜尋你要的模組。

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 pythonimport sysimport readlineimport rlcompleterimport atexitimport 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:    passatexit.register(readline.write_history_file, histfile)del os, histfile, readline, rlcompleter

匯入tab模組

>>> import tab>>> import os>>> os.                                             #已經支援tab功能了Display all 249 possibilities? (y or n)os.EX_CANTCREAT             os.ST_NOSUID                os._spawnvef(               os.getlogin(                os.seteuid(os.EX_CONFIG                os.ST_RDONLY                os.abort(                   os.getpgid(                 os.setgid(os.EX_DATAERR               os.ST_RELATIME              os.access(                  os.getpgrp(                 os.setgroups(os.EX_IOERR                 os.ST_SYNCHRONOUS           os.altsep                   os.getpid(                  os.setpgid(

可以調用shell命令
