title: How can I modify the NLTK the stop word list in python?
body: <p>I'm relatively new to the python/programming community so please excuse my relatively simple question: I would like to filter out stop words before lemmatizing a csv file. But I need the stop words "this"/"these" to be included in the final set. </p>
  
  <p>After importing nltk stop words in Python and defining them as </p>
  
  <pre><code>stopwords = set(stopwords.words('english'))
  </code></pre>
  
  <p>... How can I modfiy this set keeping "this"/"these" in? </p>
  
  <p>I know I could list every word manually except these two in question, but I was looking for a more elegant solution.</p>
