Python is a programming language.
Which version is installed
To check which versions of
python is present on our machine just run:
python -V python2 -V python3 -V
Your can choose which version should use has default with;
sudo update-alternatives --config python3
In the prompt you need to specify the program number you want to use by default.
Be careful with a selection of versions, not to touch the python (
python2), just use
Python 2.7 written in a variety of system tools, and if you try to run them the wrong version of the interpreter, then nothing happens and it could break your system.
Mint user be aware that for some reason installing
python 3.6 with
cinnamon could breaks your system as well.

Python 3.6 and
- Download Python-3.6.1.tar.xz from https://www.python.org/
