'/private/var/root/.ipython']代码有了，我们还需要将脚本放到python指定的目录下，可以使用sys.path来查看一下
（linux服务器）：一般我们会将这一类代码放在/usr/local/lib/python2.7/dist-packages目录下
（MAC存放在这个目录下）/Library/Python/2.7/site-packages

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代码中就可以import tab了
