Python on Mac OSX

[JonnyAlpha]

Hi;

I want to be able to learn and code in python on my Mac OS X 10.11.1 for projects on my Pi and have a couple of questions if I may.

1. I have python 2.7.9 installed using homebrew but how do I update it to the latest version 2 and or 3 using homebrew?

2. I have been using text wrangler as an IDE however have just come across Pycharm, as a should I install Pycharm Professional or Lite?

3. I also see Pycharm do an educational version, if I install do I need any other version of Pycharm for my own projects?

The reason for using my Mac is that I don't always have access to my Desk Based RPi and coding remotely using VNC is difficult (visually).

Many thanks for looking at these questions

Thanks
