For the available versions

See Python.org.

OS-X

Standard procedure with some “quirks”.

  • homebrew

    The “almost formally correct” use of brew, when it works proper - from the box.

    1
     brew install python

  • Install with installer

    In case of difficulties, e.g. with the git error, the on-board utilities approach may help.

    installer -pkg python-3.5.3-macosx10.6.pkg -target /
installer -pkg python-3.6.2-macosx10.6.pkg -target /
