title: Pandas: check column values by ignoring cases (convert cases)
body: <p>I am trying to check values of a pandas column using the following condition:</p>
  
  <pre><code>my_df[my_df.name.str.contains('MY_TARGET')]
  </code></pre>
  
  <p>This works fine. But since I need to convert the name column to upper case, I did the following but didn't work:</p>
  
  <pre><code>my_df[my_df.name.str.upper.contains('MY_TARGET')]
  </code></pre>
  
  <p>What's the proper way to perform the column value checks by ignoring cases? Thanks!</p>
