title: Enumeration with auto-numbering starting at 0
body: <p>Is there a better way to create a long list of enumeration with auto-numbering starting at 0? The closest that I can find is:</p>
  
  <pre><code>class Color(Enum):
      red, green, blue=range(3)
  </code></pre>
  
  <p>However, the above approach requires knowing the total items in the enumeration beforehand.</p>
