python升级

安装系统后python版本低 需要更新更高版本

1	wget https: //www .python.org /ftp/python/2 .7.9 /Python-2 .7.9.tgz

1 2 3 4 5 6 7

tar zxvf Python-2.7.9.tgz . /configure make install make mv /usr/bin/python /usr/bin/python_old ln -s /usr/local/bin/python2 .7 usr /bin/

修改yum配置文件以保证yum可用

1 2	vim /usr/bin/yum #!/usr/bin/python #修改此处为/usr/bin/python_old

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

1 2 3

wget http: //dl .fedoraproject.org /pub/epel/6/x86_64/pypy-libs-2 .0.2-1.el6.x86_64.rpm wget http: //dl .fedoraproject.org /pub/epel/6/x86_64/pypy-2 .0.2-1.el6.x86_64.rpm wget http: //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

1 2 3 4 5 6 7

try : import readline except ImportError: print ( "Module readline not available." ) else : import rlcompleter readline.parse_and_bind( "tab: complete" )

1 2	vim ~/.bashrc export PYTHONSTARTUP=~/.pythonrc.py #加入此行

vim下：

1 2 3 4 5 6

wget https: //github .com /rkulla/pydiction/archive/master .zip unzip -q master mv pydiction-master pydiction mkdir -p ~/.vim /tools/pydiction cp -r pydiction /after ~/.vim cp pydiction /complete-dict ~/.vim /tools/pydiction
