If it outputs Python 3.x.y where x and y are some integers - you are good to go. If there is an error or the version starts with 2 - install miniconda using the instructions below.
Install as part of miniconda
If you are used to getting Python on your computer in a different way then go for it - you don't have to install miniconda.
Follow instructions to install miniconda. When/if asked whether to install for all users or for the current user only - choose the latter.
In the Anaconda Prompt, run conda init bash zsh.
Open the Terminal on macOS or git-bash on Windows and check that you have conda by runing conda --version. If it outputs conda x.y.z where x, y, z are integer numbers - you are all set.
