一、 Windows下载安装python
1. 进入官网http://python.org/下载python（2.x 0r 3.x）
2. 安装：选择一个盘安装，直接下一步至完成
3. 配置环境变量：
D:Python27;
D:\Python27\Scripts;
D:\Python27\Tools\driver;
4. 验证是否生效：cmd下输入python
5. 下载的python一般都有pip，用pip下载相关库即可
二、安装pycharm
1. D:\Program Files\JetBrains\PyCharm Community Edition 2018.3.5
2. pycharm中增加svn
三、linux下安装python
1. rpm -qa yum 查询是否安装yum
yum -y install python-devel openssl openssl-devel gcc sqlite sqlite-devel mysql-devel libxml2-devel libxslt-devel

好了，大功告成。

由于Centos 6.x的系统默认都是python2.6 ，如果服务器需要用2.7环境的话每台都得手动操作升级，工作量比较大， 编写脚本提升效率。（Centos 7.x版本的默认的python都是2.7.5版本）
创建用于存放python脚本的目录
[root@server2 software]# mkdir /script/python/
[root@server2 software]# cd /script/python/
由于国外python网站下载python安装包缓慢，可以提前下载下来，和install_py27.sh放在一起，在脚本中直接解压本地文件进行安装，我已经上传到网盘
点击我下载
开始编写脚本 install_py27.sh
#!/bin/sh
# __author__ = ‘junxi‘
# This script is used by fast installed python2.7 ......
# write by 2017/04/11
echo "##############start run install for python2.7 script############"

把Python-2.7.13.tgz文件和install_py27.sh脚本下载下来，放在同一个目录下：
运行下面命令进行安装
/bin/sh install_py27.sh
安装完成后执行python查看版本
