title: Compare only first number of a tuple
body: <p>I am looking for a way to only compare the first number of a 3 number tuple.  For example let's say I have this tuple: <code>a = (255, 100, 200)</code> and this tuple <code>b = (255, 10, 20)</code>. If I were to check if they were equal using: </p>
  
  <pre><code>if a == b:
      print("equal")
  else:
      print("unequal")
  </code></pre>
  
  <p>Then I would obviously get <code>unequal</code> since they are not the same. But the first number is the same, how would I be able to compare <strong>only</strong> the first number so that I would get <code>equal</code> printed using these tuples?</p>
