title: Using MongoDB as a persistent Hashtable
body: <p>note: I am sorry if this is a stupid question!</p>
  
  <p>I have this program that generates data that it stores in pythons dictionaries.</p>
  
  <p>Since this is getting bigger and bigger, and since this is not persistent and the program has to create them all over again, each time it runs....</p>
  
  <p>I tried to use mongodb, but it seems to need both key and value to search(find function). But I have only the key, and I need the value.</p>
  
  <p>How is this done?</p>
