Broken links to install Python

Broken links to install Python

Hi

I am going to need to install Python, can't find a good step by step guide. This looks to be the latest but one of the links here is broken:

https://pitstop.manageengine.com/portal/en/kb/articles/how-to-setup-python-on-the-server

Also the video on that page is from 2016 and references sites that don't exist. 

Are there updated links and videos to install/setup Python for SDP on premise? Where do I go to install the python libraries after the initial install?
