title: Best method of saving data
body: <p>I've made a class in which I want to keep track of stats of students. I intend to make a GUI later to manipulate this data.</p>
  
  <p>My main question is: what is the best way to save and later retrieve this data?</p>
  
  <p>I've read about pickle and JSON, but I don't really get how they work (especially about how they save the data, like in which format and where).</p>
