Your next_line() function looks a little off.  Let's take a look at it:

############################################
def next_line(the_file):
    """Return next line from the trivia file, formatted."""
    line = the_file.readline()
    line = line.replace("/", "\n")
    return line
############################################

What do you want to happen here, when there are no more lines in the
file to read?
