title: Proper line-break formatting according to PEP 8?
body: <p>According to PEP 8, this is acceptable (and what I have used in the past):  </p>
  
  <pre><code>result = some_function_that_takes_arguments(
      'a', 'b', 'c',
      'd', 'e', 'f',
  )  
  </code></pre>
  
  <p>My question is, does this also apply to the function definition, so something like:  </p>
  
  <pre><code>def some_function_that_takes_arguments(
      a, b, c,
      d, e, f,
  ):
      return a,b,c,d,e,f  
  </code></pre>
  
  <p>Another example of what I have done in the past:  </p>
  
  <pre><code>if (this_is_one_thing
      and that_is_another_thing
  ):
      do_something()
  </code></pre>
  
  <p>I've been doing it this way for a while (for consistency all my lines >79 col are split this way) and am wondering what other people's thoughts are.  </p>
  
  <p>Is this clear/nice to look at? Does this adhere to PEP 8?</p>
