title: map dictionary value to the value in another dictionary in the same data file
body: <p>I'm working with a data set that contains multiple dictionaries. I want to map the value of one dictionary to the value of another dictionary. They both have the same key name. I have tried:</p>
  
  <pre><code>df_file['dict_name1']['name_of_key'].map(df_file['dict_name_2]
  </code></pre>
  
  <p>I have also substituted 'name_of_key' with its index.</p>
  
  <p>Thanks in advance</p>
