title: Does PEP 8 require whitespace around operators in function arguments?
body: <p>I have this code:</p>
  
  <pre><code>some_list = range(a, b+1)
  </code></pre>
  
  <p>After checking my coding style with <a href="http://www.vim.org/scripts/script.php?script_id=2914">pep8 plugin for vim</a>, I got this warning:</p>
  
  <pre><code>missing whitespace around operator
  </code></pre>
  
  <p>It seems that to be compliant with PEP 8 I should instead write this?</p>
  
  <pre><code>some_list = range(a, b + 1)
  </code></pre>
  
  <p>But I have read <a href="http://www.python.org/dev/peps/pep-0008/#whitespace-in-expressions-and-statements">PEP 8 - Style Guide for Python Code</a> several times and just can't find the rule applied to the warning above.</p>
  
  <p>So I want to know: when using PEP-8 style, is whitespace needed around operators(+,-,*,/,etc) in a function's arguments?</p>
