This is a free, open-source guide to installing Python 3 on a new computer. While there are multiple approaches, the goal of this site is to provide one accurate, easy-to-use solution. It is not to overwhelm a beginner.
If you disagree with a recommended approach, please submit an Issue. I'm very eager to discuss the relative merits of different approaches as they often do change over time.
