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)

🍂 “Our Lord has written the promise of resurrection, not in books alone but in every leaf of springtime.”
– Martin Luther
🌻look at the trees with fallen leaves during autumn, they keep on standing and stand strong despite many of their leaves fall down; as if they know and trust that they will not stay in that condition forever - in fact, they'll shine more beautifully soon when the spring comes. so dear, whenever you are in crestfallen, trust that that too shall pass.. be sad, but don't lose hope that tomorrow can be better☺️

🍂 something you dislike happened? you couldn't get something you wish for? you have been disappointed and someone hurt you? you lost someone? you failed at something you hope you're good at?
and you feel sad about it?
then be so. feel sad. be sad. cry if you must. cry your heart out. let it out. it heals to cry. it heals to allow yourself to feel things; be human. because yes it is difficult to go through those things.
& that doesn't mean that you are weak. to feel those feelings are not a sign of weakness at all ; just that we are human, we are born with the ability to feel those emotions.
your strength is not determined by your ability to suppress emotions, but by your ability to overcome it; by not letting it controls yourself longer than it should be.
there's light at the end of the tunnel if you keep going.

Collachrymate means to cry with someone or cry a lot until tears fall. It is an old English word from the 1500s and 1600s.
This word is not used anymore today.
Unless ofcours we revive it.😉

L'amore ed i sentimenti in generale stanno vivendo una brutta epoca, sostituiti il più delle volte da pulsioni eremitiche.

La guerra é portatrice di ingiustizie ed inganni, di questi ultimi uno dei più grandi é quello di pretendere di costruire un mondo migliore.

Non é entusiasmante prendere consapevolezza di essere quasi coetaneo di Homer Simpson.

Secondo me a livello culturale siamo immersi in una sorta di nuovo barocco, nell'accezione più deteriore del termine.

Mi sono stancato di influencer e tiktoker vari, buoni solo a pietrificare l'attenzione verso cose futili.

Trovare le parole giuste con tutti e saper cogliere le sfumature di tutte quelle che ricevo, l'ho sempre trovato uno sforzo estremo.

L'attaccamento agli oggetti é uno degli ostacoli maggiori per la nostra felicità, come se infondessimo in essi parte della nostra anima.
