Answer 1

For me brew postinstall python3 didn't work. Found this solution on GitHub homebrew issues page:

$ brew rm python 
$ rm -rf /usr/local/opt/python
$ brew prune 
$ brew install python3

Answer 2

Python3 was working successfully but without pip3. Tried many advises from stackoverflow, quora and others. (numerous installs and uninstalls)

Python3 was always fine but without pip3. Finally I downloaded Python3 from: https://www.python.org/downloads/

By simple mouse clicks and everything (Python3 + pip3) is working fine now.
