Centos7使用yum安装 python3 、 pip 、ipython
作者：互联网
新查看系统是否有可用的python3安装包
yum list python3如果没有的话 提示的以下内容！
如果没有可用的python3 安装包，则先
yum install -y epel-releaseyum install -y python3 python3-devel
在安装python之后安装ipython可以极大的方便我们学习和使用python，更多的精力集中于如何处理代码和需要解决的问题，ipython的功能还是相当不错的，那么我们如何在win系统上安装ipython呢？
安装ipython的方法：
首先确保电脑已经成功安装了python，输入命令python查看当前python是否已经成功安装
安装epel扩展源
yum -y install epel-release
执行如下：
[root@server01 work]# yum -y install epel-release
