Python versions and installing them

The beta.py is written in Python 3, and the system on which you plan to use beta.py has to have Python 3 installed on it. If you are installing Python yourself, it is recommended that you install a recent or maybe even the latest stabile release of Python 3. Loading external packages is easier if you use a Python version 3.4 or later.

If you have some Python running on your system, you can find out its version by starting in. The Python interpreter will respond, e.g.:

$ python3
Python 3.6.3 (v3.6.3:2c5fed86e0, Oct  3 2017, 00:32:08) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

If you need to install Python, the method varies according to your operating system.

On Windows, you use your browser and go to the site https://www.python.org/downloads/ and download a loader for the Windows version.

On Mac OS X you also go to the site https://www.python.org/downloads/ and load the Python package for Mac. Instructions for installing it
