Python Installer is a BASH script used to install Python from source in Ubuntu or CentOS. Since this script will go to download official Python source package, please make sure your network is alive. It requires wget utility is installed in your Ubuntu box. Actually, wget should be default installed in Ubuntu or CentOS.
Additionally, there is PIP installer script to bootstrap pip installation in Python2 as pip doesn't exist in Python2 default installation.
You actually don't make any installation. Just put this script somewhere and run it.
BASH, wget utility. Of course, you must have root permission.
