Python 自动补全模块

#!/usr/bin/env python 
# python startup 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

把上面代码保存为tab.py放置在当前系统全局环境变量下，可以使用print(sys.path)查看，如：/usr/lib64/python2.6/site-packages

• for mac

import sys
import readline
import rlcompleter

if sys.platform == ‘darwin‘ and sys.version_info[0] == 2:
    readline.parse_and_bind("bind ^I rl_complete")
else:
    readline.parse_and_bind("tab: complete")  # linux and python3 on mac
