1. 编辑文件

  # vim /usr/lib/python3.6/site-packages/tab.py 

  1import sys,readline,rlcompleter,atexit,os
  2 
  3 readline.parse_and_bind('tab: complete')
  4 histfile = os.path.join(os.environ['HOME'], '.pythonhistory')
  5 try:
  6     readline.read_history_file(histfile)
  7 except IOError:
  8     pass
  9     atexit.register(readline.write_history_file, histfile)
 10 del os, histfile, readline, rlcompleter

2. 设置环境变量

export PYTHONSTARTUP=/usr/lib/python3.6/site-packages/tab.py

写入~/.bash_profile文件保存退出然后
source ~/.bash_profile (让该配置文件生效)

3. 测试
