title: Saving and loading multiple objects in pickle file?
body: <p>I have a class that serves players in a game, creates them and other things. </p>
  
  <p>I need to save these player objects in a file to use it later.  I've tried the pickle module but I don't know how to save multiple objects and again loading them? Is there a way to do that or should I use other classes such as lists and save and load my objects in a list? </p>
  
  <p>Is there a better way?</p>
