title: Retrieving all matplotlib axes in a Figure instance: should I use figure.get_axes() or figure.axes?
body: <p>Simple question: what is the difference between</p>
  
  <pre><code>import matplotlib.pyplot as plt
  f = plt.figure()
  a = f.get_axes()
  </code></pre>
  
  <p>and</p>
  
  <pre><code>f = plt.figure()
  a = f.axes
  </code></pre>
  
  <p>for retrieving all axes in a Figure instance? Are there situations where either would be preferable?`</p>
