body: <p>I'm looking for a way to clean the following data:</p>
  <p><a href="https://i.stack.imgur.com/ITdxB.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ITdxB.png" alt="enter image description here" /></a></p>
  <p>I would like to output something like this:</p>
  <p><a href="https://i.stack.imgur.com/bdFJy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bdFJy.png" alt="enter image description here" /></a></p>
  <p>with the tokenized words in the first column and their associated labels on the other.</p>
  <p>Is there a particular strategy with Pandas and NLTK to obtain this type of output in one go?</p>
  <p>Thank you in advance for your help or advice</p>
