Return None if Dictionary key is not available
<p>I need a way to get a dictionary value if its key exists, or simply return None, if it does not.</p>

<p>However, Python returns a key_error if you search for a key that does not exist. I know that I can check for the key, but I am looking for something more explicit. Is there a way to just return None if the key does not exist ?</p>
