Мне удалось извлечь следующую строку из текстового файла

как 105 теперь извлечь из него?

Вы можете попробовать приведенное ниже регулярное выражение, чтобы получить числа внутри () paranthesis. Приведенное ниже регулярное выражение содержит строку cause , потому что было бы полезно правильно сопоставить точную строку, а также числа внутри () .

 cause (.*?(d ))
  

ДЕМОНСТРАЦИЯ

Ваш код будет,

 lineContainsCode = re.compile(r'cause (.*?(d ))')
  

Для подхода без регулярных выражений:

 code = line.split("(")[-1].split(")")[0].split("x")[-1]
# more readable:
# code = line.split("(")[-1]
#            .split(")")[0]
#            .split("x")[-1]
  

Это разделит строку на все буквальные открытые скобки и проиндексирует -1 (т. Е. захватит последний). Затем разделите это на все литералы, закрывающие скобки, и индексируйте 0 (т. Е. захватите ПЕРВЫЙ), затем разделите на все литералы "x" и индексируйте -1 (т. Е. захватите последний)
