title: get last update of a pip package programatically
body: <p>( Apologies for an issue with the initial title of this question due to a copy paste issue)</p>
  
  <p>On pypi.org I can search for packages by relevance or by "Date last updated"</p>
  
  <p>What I'd really like to search for is by relevance and "Date last update" less than (for example) a year ago.</p>
  
  <p>As the web frontend doesn't provide this I thought about writing a small script doing this for me.</p>
  
  <p>Basic idea: 
   - call pip search "name"
   - parse the output and get via an api the last changed date and filter if too old
   - try to find a way to determine the relevance (perhaps just with <a href="https://pypi.org/search/?q=searchword" rel="nofollow noreferrer">https://pypi.org/search/?q=searchword</a> )</p>
  
  <p>cross both results.</p>
  
  <p>So does anybody know how to get the last change date on pypi.org for a  given python package (or list of packages)?</p>
