title: How to plot arbitrarily many subplots in matplotlib?
body: <p>I usually do this when I want to make 2 plots:</p>
  
  <pre><code>f, (ax1, ax2) = plt.subplots(1, 2)
  </code></pre>
  
  <p>What if I have multiple lists of images and want to run the same function on each list so that every image in that list is plotted? Each list has a different number of images. </p>
