When learning python for the first time, you probably asking how to install python on lubuntu/ubuntu? the truth is python interpreter is already exist on your system.
Since lubuntu/ubuntu 14.04, python comes pre-installed, so you don't need to install anything, it's already there on your operating system waiting for your command.
To prove it, you can go ahead open terminal/ console/ command line (press CTRL + ALT + T) and then run this command :
