title: Remove specific punctuation from the list elements in Python
body: <p>From a song lyrics, I have to fetch every word as elements without including any commas (,) in element.
  For example:</p>
  
  <blockquote>
    <p>She loves you, yeah, yeah, yeah
    She loves you, yeah, yeah, yeah, yeah
    You think you lost your love
    Well, I saw her yesterday
    It's you she's thinking of
    And she told me what to say
    She says she loves you
    And you know that can't be bad</p>
  </blockquote>
  
  <p>I do split the lyrics into list elements and then made them into lower case letters. Then I tried to find commas from the list and separated them. Now I want to remove commas (,) from the list elements.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>text_file = open("Beatles.txt", "r")
  lines= text_file.read().split()
  x.lower() for x in ["A","B","C"]]
  re.findall(r"[\w]+|[.,!?;]", "Hello, I'm a string!")
  </code></pre>
  
  <p>My output is:</p>
  
  <blockquote>
    <p>['she',
     'loves',
     ',',
     'you',
     ',',
     ',',
     ',',
     ',',
     'yeah',
     ',',
     ',',
     'yeah',
     ',',
     'she',
     ',',
     'loves',
     ',',
     'you',
     ',',
     ',',
     'yeah',
     ',',
     ',',
     'yea']</p>
  </blockquote>
  
  <p>My expected output is:</p>
  
  <blockquote>
    <p>['she',
     'loves',
     'you',
     'yeah',
     'yeah',
     'she',
     'loves',
     'you',
     'yeah',
     'yea']</p>
  </blockquote>
