Фильтрация Python и извлечение текста

Вот ваше решение. Вам нужно будет настроить значения путей к входным/выходным файлам:

класс.py

import collections


def ingest(infilepath):
    """
    Read all the input from the input file.
    Store it in a dictionary so that we can parse it out later.
    We'll use a collections.defaultdict to make life easier
        {classroom name: {student name: [classes...]} }
            key'd by student name since a student can have multiple courses in a classroom
    """
    answer = collections.defaultdict(lambda: collections.defaultdict(list))
    with open(infilepath) as infile:
        classes = infile.read().split('\n\n')  # divide the input into blocks of classrooms
        classes = [c.strip() for c in classes]  # strip out any extra whitespace

    for classblock in classes:
        name, *records = classblock.splitlines()  # student records per classroom
        name = name.split(':',1)[-1].strip()
        for record in records:
            record = record.replace("(", "").replace(")", '')  # strip out the "()". We don't need that
            kvs = record.split(',')

            d = dict(kv.split(":") for kv in kvs)
            d = {k.strip():v.strip() for k,v in d.items()}

            answer[name][d['Student Name']].append(d)

    return answer


def output(outfilepath, data):
    order = ("Subject", "Time")  # the order in which we want to write the output
    with open(outfilepath, 'w') as outfile:
        for classname, d in data.items():
            for studentname, L in d.items():
                outfile.write(f"Classroom: {classname}, {studentname}, ")
                out = []  # maintain the line output in a list. We'll join everything up later
                for d in L:
                    for k in order:
                        out.append(f"{k}: {d[k]}, ")

                out = ''.join(out)  # this is the file output
                out = out.strip().rstrip(',')  # strip out the trailing ','
                outfile.write(f'{out}\n')


if __name__ == "__main__":
    print('starting')

    data = ingest('path/to/input/file')
    output('path/to/output/file', data)

    print('done')

Я использовал этот ввод (обратите внимание на пустые строки в начале файла):

Classroom arrangement : 2A-1
(Student Name: Jess, Subject: EC001, Time: 9am - 10am)
(Student Name: Whit, Subject: EC001, Time: 9am - 10am)
(Student Name: Jon, Subject: EC0011, Time: 11am - 12pm)
(Student Name: Kevin, Subject: EC011, Time: 11am - 12pm)
(Student Name: Jess, Subject: EC011, Time: 11am - 12pm)


Classroom arrangement : 1A-2
(Student Name: Jess, Subject: EC002, Time: 11am - 12pm)
(Student Name: Whit, Subject: EC002, Time: 11am - 12pm)
(Student Name: Jon, Subject: EC002, Time: 11am - 12pm)
(Student Name: Kevin, Subject: EC002, Time: 11am - 12pm)
(Student Name: Claire, Subject: EC011, Time: 2pm - 3pm)
(Student Name: Joshua, Subject: EC0011, Time: 2pm - 3pm)
(Student Name: Florence, Subject: EC011, Time: 2pm - 3pm)
(Student Name: Neil, Subject: EC011, Time: 2am - 3pm)

Я получил этот вывод:

Classroom: 1A-1, Jess, Subject: EC001, Time: 9am - 10am, Subject: EC011, Time: 11am - 12pm
Classroom: 1A-1, Whit, Subject: EC001, Time: 9am - 10am
Classroom: 1A-1, Jon, Subject: EC0011, Time: 11am - 12pm
Classroom: 1A-1, Kevin, Subject: EC011, Time: 11am - 12pm
Classroom: 1A-2, Jess, Subject: EC002, Time: 11am - 12pm
Classroom: 1A-2, Whit, Subject: EC002, Time: 11am - 12pm
Classroom: 1A-2, Jon, Subject: EC002, Time: 11am - 12pm
Classroom: 1A-2, Kevin, Subject: EC002, Time: 11am - 12pm
Classroom: 1A-2, Claire, Subject: EC011, Time: 2pm - 3pm
Classroom: 1A-2, Joshua, Subject: EC0011, Time: 2pm - 3pm
Classroom: 1A-2, Florence, Subject: EC011, Time: 2pm - 3pm
Classroom: 1A-2, Neil, Subject: EC011, Time: 2am - 3pm

Надеюсь это поможет
