title: Get latest direct message from Twitter using python/Tweepy
body: <p>I've just started using Tweepy and I'm trying to build a pretty simple bot that will use Twitter to automate a few things in my home (mostly for fun and to learn Tweepy). I've gone through the Tweepy docs and can't find out how to retrieve the latest direct message from my own account without knowing the message ID.</p>
  
  <p>I'm assuming I can use the <code>API.get_direct_messages()</code> method but it requires a message ID (which I don't know). Can anyone clue me in to the proper way to do this? I'm using Python3</p>
  
  <p>Thanks!</p>
