如何在 Mac 自制软件上更新 python3

Question

I am running python3 next to python on my mac (10.15.4). To be honest I don't exactly know how I installed that years ago. My guess is homebrew. Now I want to update to the newest version. How do I do that?

user@192-143-0-9 ~ % python --version
Python 2.7.16
user@192-143-0-9 ~ % python3 --version
Python 3.7.1
user@192-143-0-9 ~ % brew update
error: gc died of signal 9
Fast-forwarded master to origin/master.
Updated 1 tap (homebrew/core).

As of this posting python3 is on version 3.8.2 which is where I want to upgrade to. How can this be achieved?
