title: Python subset a data frame based on a variable name
body: <p>Hi I have a data frame for all stock data in my country market, the data look like this</p>
  
  <pre><code>Ticker  Date/Time   Open    High    Low Close   Volume
  AAA     7/15/2010   19.581  20.347  18.429  18.698  174100.0
  BBB     7/16/2010   19.002  19.002  17.855  17.855  109200.0
  BBB     7/19/2010   19.002  19.002  17.777  17.777  104900.0
  CCC     7/20/2010   18.429  18.429  17.084  17.354  328700.0
  CCC     7/21/2010   17.354  17.431  16.895  17.316  75800.0
  </code></pre>
  
  <p>The column Ticker has the stock name, each row is the data in one specific date.
  I would like to write a loop code that create variable with variable name is the stock name, and the variable is the subset of the whole dataframe that contain data of this stock.</p>
  
  <p>For example,</p>
  
  <p>When I call variable BBB I will get this dataframe:</p>
  
  <p>BBB</p>
  
  <pre><code>Ticker  Date/Time   Open    High    Low Close   Volume
  BBB     7/16/2010   19.002  19.002  17.855  17.855  109200.0
  BBB     7/19/2010   19.002  19.002  17.777  17.777  104900.0
  </code></pre>
  
  <p>Could you please advice how could I write this code</p>
