title: How to iterate a zip list and print each index of it after joining to lists of the same size?
body: <p>Given the variables:</p>
  
  <pre><code>X = ['a', 'b', 'c']
  Y = [1, 2, 3]
  </code></pre>
  
  <p>complete the following statement: </p>
  
  <pre><code>[print(pair) for pair in ...] 
  </code></pre>
  
  <p>so as to print to the screen pairs of elements from X and Y which occupy the same position in the index.</p>
  
  <p>I  know I can make a join <code>X</code> and <code>Y</code> and make a list using <code>list(zip(X,Y))</code> but the adding that in the statement gives an empty list. </p>
  
  <p>I can't solve this problem using the form required any help? </p>
  
  <p>thanks!</p>
