How to compare words in a string/python dictionary? : <p>I have a dictionary item in the form</p>

<pre><code> {"value for money": ["rescheduled", "cost", "low", "high", "simplicity", "booking", "price-performance", "satisfied", "satisfaction", "pricing", "prices"]}
</code></pre>

<p>I need to check whether the a  string like "I love simplicity" contains any word from this dictionary.</p>

<p>Can't figure how to define the code for this.</p>
