Imports
-------
- thou shalt not import objects, only modules
- thou shalt not import more than one module per line
- thou shalt not make relative imports
- thou shalt organize your imports according to the following template

::
  # vim: tabstop=4 shiftwidth=4 softtabstop=4
  {{stdlib imports in human alphabetical order}}
  \n
  {{OpenStack/Keystone imports in human alphabetical order}}
  \n
  \n
  {{begin your code}}


General
-------
- thou shalt put two newlines twixt toplevel code (funcs, classes, etc)
- thou shalt put one newline twixt methods in classes and anywhere else
- thou shalt not write "except:", use "except Exception:" at the very least
- thou shalt include your name with TODOs as in "TODO(waldo)"
- thou shalt not name anything the same name as a builtin or reserved word
- thou shouldeth comment profusely

Human Alphabetical Order Examples
---------------------------------
::
  import httplib
  import logging
  import random
  import StringIO
  import time
  import unittest

  import keystone.logic.types.fault as fault
  import keystone.db.sqlalchemy.api as db_api

Docstrings
----------
Add them to modules, classes, and functions:
  """Summary of the function, class or method, less than 80 characters.

  New paragraph after newline that explains in more detail any general
  information about the function, class or method. After this, if defining
  parameters and return types use the Sphinx format. After that an extra
  newline then close the quotations.

  When writing the docstring for a class, an extra line should be placed
  after the closing quotations. For more in-depth explanations for these
  decisions see http://www.python.org/dev/peps/pep-0257/

  :param foo: the foo parameter
  :param bar: the bar parameter
  :returns: description of the return value

  """
