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

We can’t leave out the signature carrot cake when talking about #OurHawkerCulture, and no, we don’t mean the dessert! Also known as Chai Tow Kway, this savoury dish is made from rice flour and radish.

Today is the first anniversary of the UNESCO inscription for Singapore’s Hawker Culture, so let’s come together to celebrate, support, and safeguard #OurHawkerCulture! #DidYouKnow many of our hawker dishes originated from the food cultures of different immigrant groups who settled in Singapore? Over time, they have evolved to become the distinctive local dishes that we love, and form an important part of our food heritage. Head down to your favourite hawker stall this week to show your support!

🍜 Ever wonder how the monthly price-based tender system for hawkers work? Every month, NEA offers vacant food and market stalls through open tenders. This ensures stalls are allocated fairly and transparently. When new hawkers successfully bid for a stall, their rent for the first three years will be based on their bid. At the end of the 3-year tenancy term, the rent is then adjusted over time to match the Assessed Market Rent (AMR), which is determined by an independent valuation. This AMR takes into account various factors such as footfall, stall sizes, and tendered stall rentals at the hawker centres. The median AMR for non-subsidised cooked food stalls has remained constant since 2019 at about $1,200 per month. 📢 While past tenders may be considered in AMR, extremely high tender bids will not be considered in the valuation of the AMR.
