title: Merge two objects in Python
body: <p>Is there a good way to merge two objects in Python? Like a built-in method or fundamental library call?</p>
  
  <p>Right now I have this, but it seems like something that shouldn't have to be done manually:</p>
  
  <pre><code>def add_obj(obj, add_obj):
  
      for property in add_obj:
          obj[property] = add_obj[property]
  </code></pre>
  
  <p>Note: By "object", I mean a "dictionary": <code>obj = {}</code></p>
