title: In python create a list with a variable in the name
body: <p>I'm trying to generate a series of (empty) lists using a for loop in python, and I want the name of the list to include a variable. e.g. y0, y1, y2 etc. Ideally looking something like this:</p>
  
  <pre><code>for a in range (0,16777216):
  global y(a)=[]
  </code></pre>
