Ранее я делал серию постов про битовые операторы. Вот вам ещё один наглядный пример как это используется в Python в модуле re. Чтобы указать флаг для компилятора нам надо указать его после передаваемой строки. Например, добавляем флаг для игнорирования переноса строки. pattern = re.compile(r"(\w+)+") words = pattern.search(text, re.DOTALL) А как указать несколько флагов? Ведь явно будут ситуации когда нам потребуется больше одного. Кто читал посты по битовые операторы уже понял как. pattern.search(text, re.DOTALL | re.VERBOSE) А теперь смотрим исходники, что находится в этих атрибутах? Не удивительно, степени двойки. Почему? Потому что каждое следующее значение это сдвиг единицы влево. >>> for n in [1, 2, 4, 8, 16, 32, 64, 128, 256]: >>> print(bin(n)) 0b1 0b10 0b100 0b1000 0b10000 0b100000 0b1000000 0b10000000 0b100000000 Чтобы было понятней, давайте напишем тоже самое но иначе, добавим ведущие нули: 000000001 000000010 000000100 000001000 000010000 000100000 001000000 010000000 100000000 Не понятно что тут происходит? Читай три поста про битовые операторы начиная с этого ➡️https://t.me/pythonotes/45 В общем, это пример применения побитовых операций в самом Python. Теперь вы знаете Python еще немного лучше) #tricks#regex#libs
