title: How to access values of dictionary when value contains another dictionary with multiple iterations on data?
body: <p>my data is</p>
  
  <pre><code> my_dict = {
       u'samosa': {
           u'shape': u'triangle',
           u'taste': None,
           u'random': None,
           u'salt': u'7.5.1'
       },
       u'idli': {
           u'color': u'red',
           u'eattime': u'134'
       },
       u'ridgegaurd': {},
       u'sambhar': {
           u'createdate': u'2016-05-12',
           u'end time': u'10655437'
       }
  }
  </code></pre>
  
  <p>There are four keys <code>samosa</code>, <code>idli</code>, <code>ridgegaurd</code> and <code>sambhar</code>.</p>
  
  <p>I don't want whole part of the values. I just want to get</p>
  
  <pre><code>value(shape) from samosa,
  values(color and eattime) from idli
  values(createdate and endtime) from sambhar
  </code></pre>
  
  <p>I want only the above values. I tried using dict but was not able to. Is it possible to write regular expressions for this?</p>
