Damos este archivo

Man: Is this the right room for an argument?
Other Man: I've told you once.
Man: No you haven't!
Other Man: Yes I have.
Man: When?
Other Man: Just now.
Man: No you didn't!
Other Man: Yes I did!
Man: You didn't!
Other Man: I'm telling you, I did!
Man: You did not!
Other Man: Oh I'm sorry, is this a five minute argument, or the full half hour?
Man: Ah! (taking out his wallet and paying) Just the five minutes.
Other Man: Just the five minutes. Thank you.
Other Man: Anyway, I did.
Man: You most certainly did not!
Other Man: Now let's get one thing quite clear: I most definitely told you!
Man: Oh no you didn't!
Other Man: Oh yes I did!
Man: Oh no you didn't!
Other Man: Oh yes I did!
Man: Oh look, this isn't an argument!
(pause)
Other Man: Yes it is!
Man: No it isn't!
(pause)
Man: It's just contradiction!
Other Man: No it isn't!
Man: It IS!
Other Man: It is NOT!
Man: You just contradicted me!
Other Man: No I didn't!
Man: You DID!
Other Man: No no no!
Man: You did just then!
Other Man: Nonsense!
Man: (exasperated) Oh, this is futile!!
(pause)
Other Man: No it isn't!
Man: Yes it is!

lo quiero dividir en dos archivos donde se vaya cargando la información dependiendo de si lo dice Man or Other

Programa:

man = []

other = []

try:

    data = open('sketch.txt')

    for each_line in data:

        try:

            (role, line_spoken) = each_line.split(':', 1)

            line_spoken = line_spoken.strip()

            if role == 'Man':

                man.append(line_spoken)

            elif role == 'Other Man':

                other.append(line_spoken)

        except ValueError:

            pass

    data.close()

except IOError:

    print('The datafile is missing!')

try:

    man_file = open('man_data.txt', 'w')

    other_file = open('other_data.txt', 'w')

    print(man, file=man_file)

    print(other, file=other_file)

    man_file.close()

    other_file.close()

except IOError:

    print('File error.')
