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

🎙 Comment by Russian Ambassador to South Africa Roman Ambarov to TASS (August 5, 2025) ❓Question: What charitable initiatives is the Russian Embassy in South Africa involved in? 💬Roman Ambarov: Russia has always been and remains a reliable friend of the Republic of South Africa—not only in the fields of political, economic, cultural, and educational cooperation, but also in providing humanitarian aid. In its work, the Russian Embassy in South Africa follows a principle supported by the President of the Russian Federation, Vladimir Putin: “African solutions to African problems.” We regularly take part in charitable initiatives organized by South Africa’s Department of International Relations and Cooperation during #MandelaDay and #MandelaMonth. In July of this year, together with other foreign diplomatic missions, we supported a primary school in Gauteng Province that is in dire need of funding by donating chalkboards and food for the students. I would like to emphasize that our charitable work is not limited to one-time actions. It is a year-round, systematic effort carried out by our Embassy staff. Two South African children’s institutions are under the care of the Russian diplomatic mission — the Bophelong Children’s Home in Mamelodi and the New Jerusalem Children’s Home in Midrand. Our diplomats regularly visit the children, show genuine interest in their lives and challenges, and offer help whenever possible. Our aim is not only to provide necessities but also to bring joy and positive emotions. It has already become a tradition to invite children from these institutions to screenings of Russian films, organized by the Embassy in one of Pretoria’s theaters. Last year, together with the parish of the Russian Orthodox Church in Johannesburg, we hosted a screening of the popular animated film Masha and the Bear for the children of New Jerusalem. The joy and excitement on the children’s faces as they clapped and sang along with Masha was the greatest reward for us. These events are usually accompanied by friendly tea parties with Russian pastries, as well as educational presentations about Russia, our culture, traditions, and holidays. As Nelson Mandela once said, “There can be no greater gift than giving one’s time and energy to help others without expecting anything in return.” We fully share this philosophy and try to embody it in our work. #RussiaHelps
