Put some debugging code into your script that keeps track of the line you
are reading. For that you can modify the next_line() routine:
current_line = 0
def next_line(the_file):
"""Return next line from the trivia file, formatted."""
global current_line
line = the_file.readline()
print("XXX CURRENT LINE", current_line, repr(line))
current_line += 1
line = line.replace("/", "\n")
return line
Then, when you run the script again, there will be a line
XXX CURRENT LINE 451 'yabba dabba doo\n'
printed right before the exception is triggered. Once you know the line
(hint: it's not actually a line in the file) the problem should be easy to
fix. (Come back here to ask for more hints if you cannot fix it.)
