python自动补全

查看python路径

>>> import sys
>>> sys.path
['', '/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']

代码

# cd /usr/lib/python2.7/site-packages/

# vim tab.py
#!/usr/bin/python

# python tab file

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
