title: How to show row dataframe?
body: <p>I have a dict of datarames <code>dict_of_dfs</code>.</p>
  <p>I try two show first row from each dataset:</p>
  <pre><code>for colsKey, colsValue in dict_of_cols.items():
      dict_of_dfs['dt_'+str(colsKey)] = pd.DataFrame(colsValue)
  
  for dfName, val in dict_of_dfs.items():
      row = dict_of_dfs[dfName].head(1)
      row
  </code></pre>
  <p>But it does not work for me.</p>
  <p>This also does not return me output pandas frame:</p>
  <pre><code>for dfName in dict_of_dfs.keys():
      dict_of_dfs['dt_12'].head(1).to_string()
  </code></pre>
