title: skip lines in a text file
body: <p>I'm very new to Python and we are using pandas to read a text file and retrieve data from specific lines.</p>
  
  <p>There are 44 lines listed in my text file but I only need from line 35 -44.  And I need to exclude everything but "President", "Took office", "Left Office", "Party".  I have this function but its not reading my df1 that will be my dataframe.</p>
  
  <pre><code>def party_list():
      df1 = pd.read_table("presidents.txt", delimiter=",",usecols=["President ", "Took office ","Left office ", "Party "])
      location1=r' /users/Paula/PycharmProjects/Spring 2018_Paula/ '
  f = open("presidents.txt",'r')
  while True:
      line = f.readline()
      if line == "":
          break
      print(line)
  </code></pre>
