title: How do I reverse a part (slice) of a list in Python?
body: <p>Why doesn't this work?</p>
  
  <pre><code># to reverse a part of the string in place 
  a = [1,2,3,4,5]
  a[2:4] = reversed(a[2:4])  # This works!
  a[2:4] = [0,0]             # This works too.
  a[2:4].reverse()           # But this doesn't work
  </code></pre>
