Should you put quotes around type annotations in python : <p>What's the difference between these two functions? I've seen people put quotes around type annotations and other times leave them out but I couldn't find why people choose to use one or the other.</p>

<pre><code>def do_something(entity: Entity):
    pass
def do_something(entity: 'Entity'):
    pass
</code></pre>

<p>Are there advantages or disadvantages to any of these?</p>
