title: Create a list of empty dictionaries
body: <p>I want to create a list of variable length containing empty directories.</p>
  
  <pre><code>n = 10 # size of list
  foo = []
  for _ in range(n)
      foo.append({})
  </code></pre>
  
  <p>Would you do this the same way, or is there something like?</p>
  
  <pre><code>a = [{}*n]
  </code></pre>
