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

🪐 Near the center of the Small Magellanic Cloud, scientists have discovered a magnetar called SXP 1062 with a magnetic field so strong it can reshape atoms and trigger intense X-ray outbursts. Magnetars are a rare kind of neutron star—ultra-dense remnants of exploded massive stars—whose magnetic fields are trillions of times stronger than Earth's and can even change the properties of empty space around them, making these cosmic magnets among the universe's most extreme phenomena. ✨ #magnetars⚡#neutronstars⚡#spacefacts⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 The star VY Canis Majoris, located about 3,900 light-years from Earth, is one of the largest known stars in the universe—so huge that if placed at the center of our solar system, its surface would reach beyond the orbit of Jupiter. This red hypergiant loses mass at an incredible rate, creating vast clouds of dust and gas that make it appear as a dim, shifting patch in telescopes rather than a sharp point of light. ✨ #unusualstars⚡#hypergiants⚡#spacefacts⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 In the spiral galaxy Messier 81, astronomers use precise observations of variable stars called Cepheids to confirm that light travels at a constant speed—299,792 kilometers per second—across millions of light-years. By timing the changes in these stars' brightness, scientists can measure vast intergalactic distances, showing that the universal speed limit of light holds true even when crossing the immense gulf between galaxies. ✨ #speedoflight⚡#Messier81⚡#spacefacts⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

The Moon takes about 29.5 Earth days to go from one sunrise to the next. Daylight lasts around 14.75 days, and night also lasts about 14.75 days. This long day and night happen because the Moon spins slowly and moves around Earth at the same time. We always see the same side of the Moon because of this. 🌕🌑 [Read more] @googlefactss#Moon#LunarDay#SpaceFacts#Astronomy

The 1967 Outer Space Treaty says no country can own the Moon, but rules about mining are still unclear. Working on the Moon could also be dangerous for human health. The Moon has water ice and rare metals that could help future space missions. But mining the Moon will damage its surface and spread potentially harmful dust. 🌕🚀 [Read more] #MoonMining#SpaceLaw#OuterSpaceTreaty#SpaceFacts@googlefactss

Pluto is slightly bigger than Russia. Pluto has a surface area of about 17.65 million km². Russia has an area of about 17.1 million km². Some sources say otherwise because of old measurements or rounding. Those sources are wrong. 🪐🌍📏 [Source 1] [Source 2] @googlefactss #Pluto#Russia#SpaceFacts#Geography#NASA#Science#planet#dwarfplanet
