Python模块tab自动补全功能

yum安装readline、readline-devel#yum install -y readline-devel下载安装setuptools#wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefe74e --no-check-certificate#tar -zxvf setuptools-0.6c11.tar.gz#cd setuptools-0.6c11#python setup.py install
下载安装readline#wget https://pypi.python.org/packages/source/r/readline/readline-6.2.4.1.tar.gz#md5=578237939c81fdbc2c8334d168b17907 --no-check-certificate#tar -zxvf readline-6.2.4.1.tar.gz#cd readline-6.2.4.1#python setup.py install

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
