Check unique values for a key in a list of dicts
<p>I have a list of dictionaries where I want to drop any dictionaries that repeat their id key.  What's the best way to do this e.g:</p>

<p>example dict:</p>

<pre><code>product_1={ 'id': 1234, 'price': 234}

List_of_products[product1:, product2,...........]
</code></pre>

<p>How can I the list of products so I have non repeating products based on their product['id']</p>
