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

This poor man passed away yesterday when his family couldn't remember his blood type. As he died, he kept insisting for his children to "be positive" What a caring father. A loving man. #Legendary 🔔@Everything_Science

"Peeing in the sink is actually the green way to go, so you're welcome. Instead of wasting 1.6 gallons of water on a flush, you pee in the sink. You then wash your hands in that very same sink, simultaneously washing down the urine and preserving nature's most precious resource." #Legendary 🔔@Everything_Science

Did you know ? In the 90s Arsenal Soccer Club had a player called David Dicks. When he was injured, the Newspaper wrote"Arsenal to play without Dicks". The coach was upset so the Newspaper changed the headline to read "Arsenal to play with Dicks out"... A record number of women attended the match. #Legendary 🔔@Everything_Science
