安装系统后python版本低 需要更新更高版本

wgethttps://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz

tarzxvfPython-2.7.9.tgz./configuremakeinstallmakemv/usr/bin/python/usr/bin/python_oldln-s/usr/local/bin/python2.7usr/bin/

修改yum配置文件以保证yum可用

vim/usr/bin/yum#!/usr/bin/python#修改此处为/usr/bin/python_old

PYPY：http://pkgs.org/search/?keyword=pypy

wgethttp://dl.fedoraproject.org/pub/epel/6/x86_64/pypy-libs-2.0.2-1.el6.x86_64.rpmwgethttp://dl.fedoraproject.org/pub/epel/6/x86_64/pypy-2.0.2-1.el6.x86_64.rpmwgethttp://dl.fedoraproject.org/pub/epel/6/x86_64/pypy-devel-2.0.2-1.el6.x86_64.rpm

注意安装顺序 先安装libs 再安装pypy 最后安装devel

经测试 pypy的效率要比cpython高大约三到四倍

实现Python的交互模式下tab自动补全和vim下python tab自动补全:

下面是.pythonrc.py的内容

try:importreadlineexceptImportError:print("Modulereadlinenotavailable.")else:importrlcompleterreadline.parse_and_bind("tab:complete")

vim~/.bashrcexportPYTHONSTARTUP=~/.pythonrc.py#加入此行

vim下：

wgetunzip-qmastermvpydiction-masterpydictionmkdir-p~/.vim/tools/pydictioncp-rpydiction/after~/.vimcppydiction/complete-dict~/.vim/tools/pydiction
