Python on a Mac

Don't use the default Python installation: it isn't the latest and can result in permissions issues and pacakges being wiped after an OSX update.

  1. Install it from Homebrew:
    brew install python
  2. Check which version of Python you're using:
    which python
    If it responds '/usr/bin/python' you're using the system one. Read on.
  3. Edit the paths to include your Homebrew Python install:
    sudo vi /etc/paths
  4. Prepend /usr/local/bin to the list of locations
  5. Check the result:
    Should result in the Homebrew version.
