这样就把python自动补全的功能安装完毕



如果想启动python编辑器就自动加载，则需要做以下操作


切换到python目录，我的系统是/usr/lib/python2.7

编辑startup.py脚本

#!/usr/bin/python
import readline, rlcompleter
readline.parse_and_bind("tab: complete")

授权

#chmod 755 /usr/lib/python2.7/startup.py


修改根目录的.bashrc文件

添加如下一行

export PYTHONSTARTUP=/usr/lib/python2.7/startup.py


重新加载环境变量

#source .bashrc


这样再进入python编辑器就可以自动补全啦
