## 配置使用 ##

哪个python?

如果anaconda的PATH没有添加到~/.bashrc文件中，那么每次使用之前，请在当前终端执行如下命令：

如果已经添加到~/.bashrc中，则每次启动终端后会自动调用该anaconda环境。

执行python

在当前终端执行“python”命令，得到：

Python 2.7.13 |Anaconda 4.4.0 (64-bit)| (default, Dec 20 2016, 23:09:15) 
    [GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.

## 进阶 ##

如果我们同时安装的了anaconda2和anaconda3，那么可以在~/.bashrc中添加如下命令：

alias py2='export PATH=$HOME/anaconda2/bin:$PATH'
    alias py3='export PATH=$HOME/anaconda2/bin:$PATH'

当想使用python2的时候，就输入py2；同理，输入py3。
