Step to install python on Linux system

1. 下载python源码包并解压缩

$ wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz
tar xf Python-3.*

2. 进入到文件夹 build源码

cd Python-3.*
#Prepare compilation 
./configure
#Build
make

3. 将python安装到系统

#Install
make install

OR if you don't want to overwrite the python executable (safer, at least on some distros yum needs python to be 2.x, such as for RHEL6) - you can install python3.* as a concurrent instance to the system default with an altinstall:

make altinstall
