1. PEP8 Style Guide for Python Code

    Two good reasons to break a particular rule:     (1) When applying the rule would make the code less readable, even for
someone who is used to reading code that follows the rules.     (2) To be consistent with surrounding code that also breaks it (maybe for
historic reasons) -- although this is also an opportunity to clean up
someone else's mess (in true XP style).
