title: How to get instagram username from username ID without API in Python?
body: <p>I'm trying to find a way to get instagram username from the username ID in Python.
  What I found so far is this:</p>
  
  <pre><code>https://api.instagram.com/v1/users/[USER-ID]?access_token=[YOUR-ACCESS-TOKEN]
  </code></pre>
  
  <p>I have a token number, but it only works for users added to sandbox. For other users I receive the following error:</p>
  
  <pre><code>{"meta": {"code": 400, "error_type": "APINotFoundError", "error_message": "this user does not exist"}}
  </code></pre>
  
  <p>I'm searching a solution for hours with no luck so far. 
  Is there a way to arrive to the same result without using a token? </p>
  
  <p>Thanks a lot!</p>
