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)

The United States is depleting its tungsten reserves, a resource critical to the military-industrial complex, according to Foreign Policy. 🔗
Tungsten is essential for manufacturing armor-piercing ammunition, missile components, and aviation equipment. Currently, the United States does not commercially produce tungsten and relies heavily on imports, primarily from China, which dominates the global market. 🌍
Since the escalation of conflict in the Middle East, tungsten prices have surged by over 500%. 📈 Expanding production remains challenging due to limited industrial capacity. Sources indicate that the United States is already confronting a tungsten shortage with no immediate resolution in sight. Even prior to the conflict, the Pentagon sought to reduce its dependence on tungsten, though the extent of their success remains uncertain. ⚙️🇺🇸

News: Risk of renewed #conflict mounts as troop movements reported near #Eritrea–#Tigray border—Bloomberg
Addis Abeba—Ethiopia and Eritrea are deploying troops and military equipment near the northern Tigray region, raising the risk of renewed conflict in the Horn of Africa, Bloomberg reported, citing regional diplomats.
Sources familiar with the matter told Bloomberg that Ethiopian troops and equipment have been moved northward, including through Bahir Dar, while Eritrean forces have also deployed to areas inside Tigray.
Prime Minister Abiy Ahmed this week reiterated Ethiopia’s longstanding ambition to secure access to the Red Sea, describing maritime access as key to overcoming logistical constraints on economic growth.
Eritrean state television also broadcast a naval parade in Massawa last week, marking the anniversary of the city’s capture in 1990.
