title: python: adding any number of days to date
body: <p>I am hoping someone can point me in the right direction in working with dates and timedelta.</p>
  
  <p>my understanding is that to add any number (ex: 10 days) to a date, you need to convert it to a timedelta.
  if that is correct, how can I add any number to a date when it is an integer?</p>
  
  <p>any documentation or links would be great - thank you.</p>
  
  <p>code example, my date is as follows: </p>
  
  <pre><code>x = 20100103 (formatted as YYYYMMDD)
  </code></pre>
