body: <p>There is a list filled with tuples, like  </p>
  
  <pre><code>pairs = [('cheese', 'queso'), ('red', 'rojo'), ('school', 'escuela')]  
  </code></pre>
  
  <p>How do I find the length of, like, first tuple? <code>len(pairs)</code> returns me 3 and <code>len(pairs[])</code> returns error. How do I get the length of a tuple inside the list?</p>
