title: Shopify Python API - how to search for a product
body: <p>I have built a django app that is the primary store for my products. From this, I publish products to my Shopify Store. Now my django app knows first when my product goes out of stock.  </p>
  
  <p>Question:
  What options do I have to search for products using the Python API? Can I search by Title, Variant SKU?</p>
  
  <p>Is storing the generated ID while publish the <em>only</em> means to get a handle on the product later?</p>
  
  <p>I want to do this - so that I can mark the products Out Of stock, in a batch process, for example.</p>
