title: PEP8 E226 recommendation
body: <p>The <a href="http://pep8.readthedocs.org/en/latest/intro.html#error-codes" rel="noreferrer">E226</a> error code is about <em>"missing whitespace around arithmetic operator"</em>.</p>
  
  <p>I use <a href="http://damnwidget.github.io/anaconda/" rel="noreferrer">Anaconda</a>'s package in Sublime which will highlight as a PEP8 E226 violation for example this line:</p>
  
  <pre><code>hypot2 = x*x + y*y
  </code></pre>
  
  <p>But in <a href="https://www.python.org/dev/peps/pep-0008/" rel="noreferrer">Guido's PEP8 style guide</a> that line is actually shown as an example of <a href="https://www.python.org/dev/peps/pep-0008/#other-recommendations" rel="noreferrer">recommended use</a> of spaces within operators.</p>
  
  <p>Question: which is the correct guideline? Always spaces around operators or just in some cases (as Guido's recommendation shows)?</p>
  
  <p>Also: who decides what goes into PEP8? I would've thought Guido's recommendation would pretty much determine how that works.</p>
