| If you need to install Python, you may as well download the most recent stable version. This is the one with the highest number that isn't marked as an alpha or beta release. Please see the [[http://www.python.org/downloads/|Python downloads]] page for the most up to date versions of Python 2 and Python 3. They are available via the yellow download buttons on that page. | ==== Arch Linux ==== |

Downloading Python
On many systems Python comes pre-installed, you can try running the python command to start the Python interpreter to check and see if it is already installed. On windows you can try the py command which is a launcher which is more likely to work. If it is installed you will see a response which will include the version number, for example:
Python 3.9.6 (tags/v3.9.6:db3ff76, Jun 28 2021, 15:26:21) [MSC v.1929 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.
If you don't see this, you will need to install Python on your system.
If the version number is Python 2.x.y (where x and y are any number) you are using Python 2 which is no longer supported and is not a good choice for development. You can try running python3 to see if there is also a Python 3.x.y version installed, if not you'll want to install the latest version of Python.
If you do not have Python installed or need a newer version you can go to:
