title: With Python, can I keep a persistent dictionary and modify it?
body: <p>So, I want to store a dictionary in a persistent file. Is there a way to use regular dictionary methods to add, print, or delete entries from the dictionary in that file?</p>
  
  <p>It seems that I would be able to use cPickle to store the dictionary and load it, but I'm not sure where to take it from there.</p>
