title: Python: quick way to replace all occurances of a specific word in a list?
body: <p>I have a list of words. It's pretty large (len(list) ~ 70,000).
  I'm currently using this code:</p>
  
  <pre><code>replacement = "bla"
  for word in data:
      if (word in unique_words):
          word = replacement
  </code></pre>
  
  <p>This code take a <em>while</em> to perform the operation. Is there a quicker way to do this?</p>
