Error with remove stopwords

Can someone help me with the function remove_stopwords? I have used str.replace method, I wanted to get some hints as to what to use instead. i am getting 15/20 grades for the function.

Please click my name and message the code for remove_stopwords

There is still a problem that there is no space at of end of sentence. So, you may not end up removing all stopwords. Please do the following:

  1. Use split() method to create a list of words from the sentence.
  2. Filter out stopwords from the list.
  3. Use string join method to join the non-stopwords and return the result.

Thank you, your suggestion helped
