title: Printing dictionary where the keys are static, and values dynamic in terminal
body: <p>I have a REST URL 
  It returns a large JSON object as a dictionary.</p>
  
  <pre><code>{"id": 1, "name" : bobert, "cash" : 100}
  </code></pre>
  
  <p>I'm doing the basic print key, value, however here's the challenge:</p>
  
  <p>I need it to look like this.</p>
  
  <p>id   :  1
  name :  bobert
  cash :  100</p>
  
  <p>^^^ I need the keys "(id, name, cash) to persist on the screen, and only the values (1, bobert, 100) to update with each new request.</p>
  
  <p>This is similar to the problem of updating a single line like a progress bar, but for multiple lines.</p>
  
  <pre><code>for keys, values in my_resp.items():
    print ('  {}  =  {}  '.format(keys, values))
  </code></pre>
  
  <p>That code is the basic idea, but I need the keys to persist, and values to be updated.</p>
  
  <p>I've looked at curses (which I think is too complicated for this)
  And also looked the sys.stdout.write but that only appears to work for 1 line at a time.</p>
