title: similarity calculus between lists of tuples with different length
body: <p>I need to generate a dataframe or matrix with  distance between  lists of tuples which are of different lengths (any distance showing similarity other than matrix similarity) with Python.</p>
  <pre><code>x=[(15,7),(12,7),(80,3),(10,8)]   y=[(12,4),(11,9)]    z=[(1,1),(16,7),(0,3),(10,5),(3,44)]
  </code></pre>
