title: What exactly is a python library?
body: <p>Sorry for such a basic question, I couldn't really find an answer through google that I could understand.</p>
  
  <p>What exactly is a python library in laymans terms?  It seems like its something that you download or import and move into a certain folder to add a specific functionality in python?</p>
  
  <p>If I download a library for python, does it go in /usr/lib ?</p>
  
  <p>Any help would be appreciated I'm really lost on this!</p>
