title: Python/Boto - Writing to AWS CloudWatch Logs without sequence token
body: <p>I am trying to send logs to AWS CloudWatch Logs using Python and Boto framework. I am doing this:</p>
  
  <pre><code>res=logs.put_log_events("FOO", "BAR",
       [{'timestamp':int(round(time.time() * 1000)),
         'message':time.strftime("%m/%d/%Y %H:%M:%S")+' Scheduled  monitoring check' }], 
       sequence_token=None)
  </code></pre>
  
  <p>I get an error each time I run:</p>
  
  <pre><code>boto.logs.exceptions.InvalidSequenceTokenException: InvalidSequenceTokenException: 400 Bad Request
  {u'message': u'The given sequenceToken is invalid. The next expected sequenceToken is: 49540113336360065754596906019042392283494234157161146226', u'expectedSequenceToken': u'49540113336360065754596906019042392283494234157161146226', u'__type': u'InvalidSequenceTokenException'}
  </code></pre>
  
  <p>It is somewhat impractical for me to store that token. It makes no sense, why can't I just append to the log stream ?</p>
  
  <p>How can I get around this ?</p>
