python3和python2虽然语法有很大区别，但python2和python3源码安装是一样的， 这里以python3安装为例：
======================python3安装==================================
yum install -y openssl openssl-devel gdbm gdbm-devel gcc gcc-c++ bzip2 bzip2-devel lzma xz-devel
yum install -y xz-compat-libs ncurses ncurses-devel sqlite sqlite-devel readline readline-devel tk tk-devel

>>>
=====================Ipython安装====================================================
Ipython安装,ipython 可以补全
