title: Python - How to count specific section in a list
body: <p>I'm brand new to python and I'm struggling how to add certain sections of a cvs file in python. I'm not allowed to use "import cvs"
  I'm importing the TipJoke CVS file from <a href="https://vincentarelbundock.github.io/Rdatasets/datasets.html" rel="nofollow noreferrer">https://vincentarelbundock.github.io/Rdatasets/datasets.html</a></p>
  
  <p>This is the only code I have so far that worked and I'm at a total loss on where to go from here.</p>
  
  <pre><code>if __name__ == '__main__':
  from pprint import pprint
  from string import punctuation
  f = open("TipJoke.csv", "r")
  tipList = []
  for line in f:
      #deletes the quotes
      line = line.replace('"', '')
      tipList.append(line)
  pprint(tipList[])
  </code></pre>
  
  <p>Output:</p>

  <p>I'm currently trying to find the Total number of entries of the specified card type and the Percentage of tips given for the specified card type with two decimal places of precision. The tip column is the 0 or 1 right after the card type (None, Ad, Joke).</p>
