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)

Nifty 50 very important levels are ahead
24355 to 23900
#StockMarketCrash is loading but not before the top cycle 27000 to 28000 completes and once it is done the one of the main cycles will take over on top.
#Budget2026
23900 was given months and highs were broken since then ranging on top and now retraced.
as long as the 23900 to 24355 holds and above that is clear upside only.
from there levels check for confirmations and once its clear and it forms lows here and it must hold there and price bounces nicely and goes up
long term cycle is 26525 and breaking that would be 27000 and next would be 28000 and will update once reached 27000.
bank nifty previous levels were 59860 and it's where the high was today almost exact it worked very well in nifty because of gift nifty in that cycle was complete and also bank nifty coincided
once this current upside is done it will all crash this year after highs around 28000 or so will update exact as price approaches near it.
