title: What does the return value of gc.collect() actually mean?
body: <p>When I do <code>gc.collect()</code> in my Python script, it returns values like 86, 14, etc. </p>
  
  <p>I understand that this call performs garbage collection and I've already gone through the documentation <a href="https://docs.python.org/3/library/gc.html#gc.collect" rel="noreferrer">here</a>. But can someone explain through an example what do the numbers <em>actually mean</em>?</p>
