replace the punctuation with whitespace
<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>
