title: How is it best to upgrade to python 3 on a Mac with Catalina OS?
body: <p>I have recently done a fresh install of Mac OS Catalina on my iMac and I noticed that it already has python 3.7.3 and the latest pip3 installed. I would like to upgrade to 3.8. How can this be done? Can I upgrade the python 3 installation already on Catalina somehow or is it best to install another instance of python 3 with Homebrew? If the latter, how do I point python3 and pip3 to 3.8 and would that mess up the OS in anyway? </p>
