Python 'self'

"The reason you need to use self. is because Python does not use the @ syntax to refer to instance attributes. Python decided to do methods in a way that makes the instance to which the method belongs be passed automatically, but not received automatically: the first parameter of methods is the instance the method is called on. That makes methods entirely the same as functions, and leaves the actual name to use up to you (although self is the convention, and people will generally frown at you when you use something else.) self is not special to the code, it's just another object."

"Because explicit is better than implicit."

Python: Underscore In Front of Variable

"In addition, the following special forms using leading or trailing underscores are recognized (these can generally be combined with any case convention): _single_leading_underscore: weak "internal use" indicator. E.g. "from M import *" does not import objects whose name starts with an underscore."

Installing PyGame on Mac

Linux and Windows seem to have more straightforward installations. This worked for me on Mac.

brew install python
/usr/local/share/python/easy_install mecurial

brew install sdl
brew install sdl_mixer
brew install sdl_ttf
brew install sdl_image

hg clone https://bitbucket.org/pygame/pygame
cd pygame
/usr/local/bin/python setup.py install

You can verify proper installation by typing in terminal:

python

import pygame
