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)

📰 China’s Record Drills: Taiwan Encircled, World on Edge
China just launched its largest war games around Taiwan to date, sending a clear message: Beijing can cut off the island from the outside world if conflict erupts. The drills, dubbed “Justice Mission 2025,” involved troops, warships, fighter jets, and artillery, with live fire and simulated strikes designed to test Taipei’s defenses and U.S.-made weapons.
“Conducting live-fire exercises around the Taiwan Strait ... would not only constitute military pressure on us, but could also pose more complex challenges and impacts for the international community and neighbouring countries.”
— Hsieh Jih-sheng, Taiwan’s deputy chief of defence
The drills covered a record seven zones, some closer to Taiwan than ever before, and forced the cancellation of hundreds of flights. China’s military released propaganda videos showing futuristic tech—automated robots, microdrones, and weaponised robotic dogs—while Taiwan’s defence ministry responded with its own footage of U.S.-made HIMARS rocket systems.
Analysts say these exercises blur the line between training and actual preparation for invasion, aiming to give the U.S. and allies minimal warning. China’s state media insists the drills are a response to increased U.S.-Taiwan military cooperation, while Taiwan’s government remains on high alert, coordinating rapid-response exercises and deploying ships to face off with Chinese vessels.
So, is this just another show of force—or the opening act of something far more dangerous?
