title: Assign a letter to a value if that value falls within a range of possible numbers
body: <p>Simple question, but I can't figure out a way to assign a letter to an input number without using a whole bunch of if statements. </p>
  
  <p>What I'm after is: </p>
  
  <p>0-11 : A</p>
  
  <p>12-23 : B</p>
  
  <p>24-35 : C</p>
  
  <p>and so on.</p>
  
  <p>I first thought to use modulo, but that divides numbers sequentially between a range.</p>
  
  <pre><code>import string
  letters = string.ascii_lowercase
  for i in range(95):
      if 0 &lt; i &lt; 12:
          well = letters[i%12]
  </code></pre>
  
  <p>Is there something similar to modulo I can use?</p>
