Am new to linux and i dont have any gui installed. I would like 2 know which website 2 go 2, 2 download the gui and how do i install it after downloading. And how do i run installed programs such as python?
Depending on what OS you have (Linux is the Kernel), you can add many different desktop environments such as Gnome, KDE and XFCE.
The chances are your OS has a pre-defined list of repositories (a bit like a big book of sources). Your OS shall also have a package management software, for example in Debian it is apt.
Depending on these factors shall depend on what desktop environment you can install, find out your package manager, pick a desktop and check it's compatability and then do a quick google search. The chances are you can install it in a couple of commands.
