    Have you tried solving that yourself? – vaultah Mar 04 '16 at 19:41

  • Try writing something you hope will work, then (if it doesn't), try asking why – holdenweb Mar 04 '16 at 20:04
  • I tried since last night... but okay for the future reference, I'll post my progress as well. Thank you. – Chang Dae Hyun Mar 04 '16 at 20:51

If I recall correctly, you would do it like this:

def every_second_line(report_location):
    """ This code will return every second line with trailing whitespace stripped."""
    report = open(report_location, rb+)
    second_lines = [a.strip() for a in report.readlines()[1::2]]

    return second_lines

I don't have Python with me at the moment, but this should work. Good luck!
