vim tab.py
-------------------------------------
#!/usr/bin/env python
# python startup file
import sysimport readline
import rlcompleter
import 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:
pass
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter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.....
>>> import tab>>> sys.sys.__class__( sys.__subclasshook__( sys.exitfunc( sys.path_importer_cache sys.__delattr__( sys._clear_type_cache( sys.flags sys.platform sys.__dict__ sys._current_frames( sys.float_info sys.prefix sys.__displayhook__( sys._getframe( sys.float_repr_style sys.ps1 sys.__doc__ sys._mercurial sys.getcheckinterval( sys.ps2 sys.__excepthook__( sys._multiarch sys.getdefaultencoding( sys.py3kwarning sys.__format__( sys.api_version sys.getdlopenflags( sys.py
