Running open with or without rU generates this message when reading a CSV file with CR line endings:
DeprecationWarning: 'U' mode is deprecated
  with open(csvfile, mode='rU', newline='') as cf:
Traceback (most recent call last):

    main()

    header = next(rdr) # assume first row is header
_csv.Error: new-line character seen in unquoted field - do you need to open the file in universal-newline mode?
