python中添加tab模块

1.新建一个tab.py的模块文件

#!/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

2.在python中运行命令sys.path查看python路径

3.将cp tab.py

4.在python中引用tab模块
