title: Python SDK list_computers method security_updates object always None
body: <p>Trying to add to reporting value for security updates on computer objects.  using the list_computers method with the python SDK and using AWS TM 11.3.184.  </p>
  
  <p>Method reference: <a href="https://automation.deepsecurity.trendmicro.com/article/11_3/api-reference?platform=aws#operation/listComputers" rel="nofollow noreferrer">https://automation.deepsecurity.trendmicro.com/article/11_3/api-reference?platform=aws#operation/listComputers</a> </p>
  
  <p>According to the SDK documentation there should be a securityUpdates object inside the return (really security_updates in python return) that contain the status object inside.  However, testing seems to show while security_updates exists its value is always None</p>
  
  <p>Note: Btw secondary issue to note is the python SDK API reference shows camelcase (assuming as Java SDK returns as such) but the real return is snake case.   </p>
  
  <p>I have crosschecked with console and looking at a computer that has the security update status set "Up-to-Date" the object in API call return still shows None instead.  In code snipped can see the end of the computer object return for this case</p>

  <p>Expectation is like in the API documentation a return similar to this instead of None (in snake case of course in reality, this is copied from API ref):</p>
