title: Formatting a variable with another variable in Python
body: <p>Let's suppose I have a <code>for</code> loop. After each loop, I get a result that I want to store in a list.
  I want to write something like this but it's not working: </p>
  
  <pre><code>for i in range(50):
      "result_%d" %i = result
  </code></pre>
  
  <p>Supposing that <code>result</code> is a list containing the results after each loop.
  I want to do that in order to have a different list for each result, so I could be able to use them after the loop is finished.</p>
  
  <p>Is there any way to do that?</p>
  
  <p>Note: I thought about storing all the result lists in one big list. But won't that be heavy for the code? Noting that each result list has a size of 60.</p>
