title: Splitting list element into individual single elements in another list
body: <p>currently I have two list, ListofComments and ListofWords. ListofComments has many words in its element. For example.
  ListofComments[0] = 'I love python'
  ListofComments[1] = 'I hate python'
  but currently i was able to only split it into individual words for the last element of ListofComments. Below is what I have currently.</p>
  
  <pre><code> for x in range(0, 58196):
      ListofWords = (re.sub("[^\w]", " ", ListofComments[x]).split())
  </code></pre>
  
  <p>I understand that perhaps another loop is needed but i can't exactly pinpoint how to go about solving this issue. The desire output would be having these ListofWords[0] = 'I' ListofWords[1] = 'love' ListofWords[2] = 'python' ListofWords[3] = 'I' LstofWords[4] = 'hate' ListofWords[5] = 'python' </p>
