import readline,rlcompleter

### Indenting
class TabCompleter(rlcompleter.Completer):
    """Completer that supports indenting"""
    def complete(self, text, state):
        if not text:
            return ('    ', None)[state]
        else:
            return rlcompleter.Completer.complete(self, text, state)

readline.set_completer(TabCompleter().complete)

### Add autocompletion
if 'libedit' in readline.__doc__:
    readline.parse_and_bind("bind -e")
    readline.parse_and_bind("bind '\t' rl_complete")
else:
    readline.parse_and_bind("tab: complete")

### Add history
import os
histfile = os.path.join(os.environ["HOME"], ".pyhist")
try:
    readline.read_history_file(histfile)
except IOError:
    pass
import atexit
atexit.reGISter(readline.write_history_file, histfile)
del histfile

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

>>> import sys
>>> sys.path['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client']

  一般我们会将这一类代码放在/usr/local/lib/python2.7/dist-packages目录下

 

mv tab.py /usr/local/lib/python2.7/dist-packages

ok,下面我们可以直接导入tab模块,马上体验一下tab补全吧.....
