title: Shopify Python API: How do I add a product to a collection?
body: <p>I am using the Shopify Python API in an django app to interact with my Shopify Store. </p>
  
  <p>I have a collection - called - best sellers.</p>
  
  <p>I am looking to create a batch update to this collection - that is add/remove products to this collection. However, they python API docs does not seem to say much about how to do so. How do I fetch a collection by name? How do I add a product to it?</p>
  
  <p>Thank you for your help.</p>

  <p>This is what I found</p>
  
  <blockquote>
    <blockquote>
      <blockquote>
        <p>x=shopify.CustomCollection.find(handle="best-sellers")</p>
        
        <p>y=shopify.Collect() #creates a new collect</p>
        
        <p>p = shopify.Product.find(118751076) # gets me the product</p>
      </blockquote>
