title: How to change datatypes in tuples?
body: <p>I'm working with a list of int's and floats, and trying to change the second parameter to string.</p>
  
  <p>What I have is something like this:</p>
  
  <pre><code>array = [(12.0, 23),(9.0, 24)]
  </code></pre>
  
  <p>What I want is:</p>
  
  <pre><code>array = [(12.0, '23'),(9.0, '24')]
  </code></pre>
  
  <p>I tried using a simple for, as shown below:</p>
  
  <pre><code>for i in range(len(array)):
    array[i][1] == str(array[i][1]) 
  </code></pre>
  
  <p>Could anyone explain me why this does not work, and if so, an easier way to do this?
  Thank you very much!</p>
