title: replace the punctuation with whitespace
body: <p>I have a problem with the code and can not figure out how to move forward.</p>
  
  <pre><code>tweet = "I am tired! I like fruit...and milk"
  clean_words = tweet.translate(None, ",.;@#?!&amp;$")
  words = clean_words.split()
  
  print tweet
  print words
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>['I', 'am', 'tired', 'I', 'like', 'fruitand', 'milk']
  </code></pre>
  
  <p>What I would like is to replace the punctuation with white space but do not know what function or cycle use. Can anyone help me please?</p>
