body: <p><a href="https://i.stack.imgur.com/ZD6s8.png" rel="nofollow noreferrer">enter image description here</a></p>
  <p>Here is a data set is given.
  The rows contain the different platforms.
  The columns are the different genres.
  We have the score associated with the platforms and the genres.
  I have to find out the worst performing genre on PC. I used :</p>
  <blockquote>
  <p>genre = ign_data.loc['PlayStation Vita'].min()</p>
  </blockquote>
  <p>I am able to get the worst performing score, However I am not able to extract the corresponding column associated with it. Does anyone know the solution to it?</p>
