Linux设置python自动tab自动补全

1.安装readline模块。

sudo apt-get install readline*

2.创建文件~/.pythonstartup,内容如下

# 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 

3.在~/.bash_profile中添加环境变量

export PYTHONSTARTUP=~/.pythonstartup

4.刷新配置

source .bash_profile
