Diff multidimensional dictionaries in python
<p>I have two dictionaries</p>

<pre><code>a = {'home': {'name': 'Team1', 'score': 0}, 'away': {'name': 'Team2', 'score': 0}}
b = {'home': {'name': 'Team1', 'score': 2}, 'away': {'name': 'Team2', 'score': 0}}
</code></pre>

<p>The keys never change but I want to get that ['home']['score'] has changed </p>

<p>Any easy way to do this?</p>
