Installation of homebrew - confusion over version and previous installation - how do I get everything installed without warnings?

Question

I have just installed homebrew and I have installed Python 3.7.5, although if I enter python --version , it tells me I have 3.6.4

If I use brew info python , it tells me I have Python 3.7.5, but a number of warnings appear. This includes unbrewed dylibs, some config files found outside my system or homebrew directories, as well as unbrewed header files, unbrewed.pc files and unbrewed static static libraries.

Running which python gives me /usr/bin/python

Echo $PATH gives me /Library/Frameworks/Python.framework/Versions/3.6/bin:/anaconda3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin

This is the result, I think of a previous Anaconda installation.

I want to start from scratch with a clean version of Python using homebrew.

What should I do? Any help is appreciated please.

Edit the file ~/.bash_profile and set your PATH environment variable to:

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin
