title: How to get rows which match a list of 3-tuples conditions with SQLAlchemy
body: <p>Having a list of 3-tuples :</p>
  
  <pre><code>[(a, b, c), (d, e, f)]
  </code></pre>
  
  <p>I want to retrieve all the rows from a table where 3 columns matches the tuples. FOr this example, the query <code>WHERE</code> clause could be something like this :</p>
  
  <pre><code>   (column_X = a AND column_Y = b AND column_Z = c)
  OR (column_X = d AND column_Y = e AND column_Z = f)
  </code></pre>
  
  <p>How can I create such a request using SQLAlchemy ? In my case the 3-tuples list will contains hundred of elements, and I'm looking for the best scallable solution.</p>
  
  <p>Thanks for your help,</p>
