title: How to deal with Pylint's "too-many-instance-attributes" message?
body: <p>I have just tried to lint some code with Pylint, and the last remaining error is</p>
  
  <pre><code>R0902: too-many-instance-attributes (8/7)
  </code></pre>
  
  <p>I understand the rationale behind limiting the number of instance attributes, but seven seems a bit low. I also realise that the linter should not have the last word. However, I would like to know what I should be doing instead of:</p>
  
  <pre><code>def __init__(self, output_file=None, output_dir=None):
      """
      Set the frobnicator up, along with default geometries
      """
  
      self.margin = 30
  
      self.pos = [0, 0]
      self.sep = [5, 5]
  
      self.cell = [20, 20]
  
      self.frobbr = library.Frobbr()
  
      page = self.frobbr.get_settings('page')
  
      self.lim = [page.get_width() - self.margin,
                  page.get_height() - self.margin]
  
      self.filename = output_file
      self.moddir = output_dir
  </code></pre>
  
  <p>Should I package the geometries up into a dict, do something else to stop Pylint complaining, or just ignore it (which I don't really want to do)?</p>
