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

Environmental Stickers for Vehicles in Uzbekistan — Free and Voluntary 🚗 📅 On December 19 of this year, the National Committee for Ecology and Climate Change, together with relevant ministries and agencies, held an awareness-raising event at the “Fayzobod” Vehicle Diagnostic Inspection Center located in the Mirabad district of Tashkent. The center operates under the Road Safety Service of the Public Security Department of the Ministry of Internal Affairs. The event was attended by representatives of government bodies, civil society institutions, non-governmental non-profit organizations, political parties, citizens’ self-governance bodies (mahallas), as well as mass media representatives. ♻️ What is an environmental sticker? An environmental sticker is not a fine or a restriction, but an indicator of a vehicle’s environmental condition. It is a symbol of the driver’s responsibility and contribution to clean air and a sustainable future for the country. ❗️Important: Environmental stickers are provided free of charge. 📍 How and to whom are the stickers issued? Environmental stickers are issued: free of charge based on the vehicle owner’s voluntary electronic application; during vehicle registration or re-registration, based on the results of the first free diagnostic inspection. 🚦 Environmental categories of vehicles Within the framework of the system, vehicles will be gradually classified into the following categories: 🟢 “clean” 🟡 “moderate” 🔴 “polluting” The category is determined according to environmental standards, while the color of the sticker reflects the level of the vehicle’s impact on the environment. 🔄 Owners of vehicles classified as “moderate” or “polluting” have the right once a year to undergo a free re-diagnostic inspection, improve the environmental category of their vehicle, and receive a new environmental sticker. 🌱 Why is this important? Despite the measures being taken, air pollution levels in the country remain high. An extremely dry autumn, annual reductions in water resources, as well as emissions from industrial enterprises and vehicles have led to the fact that Tashkent and other settlements are among the regions with high levels of air pollution. 📊 According to medical statistics, in 2024, 11,034.8 cases of respiratory and allergic diseases per 100,000 population were recorded nationwide, a significant proportion of which occurred among children. Air pollution directly affects public health, socio-economic development, and the international image of the country. 📜 Legal framework The “Environmental Transport” system is being introduced in accordance with the Resolution of the Cabinet of Ministers of the Republic of Uzbekistan dated November 28, 2025, No. 750, and will be implemented in stages: 2025–2027 — Tashkent city 2028–2030 — Nukus city and regional centers 2031–2034 — all other regions of the country 🏙 Environmental zones The boundaries of environmental zones will be determined by local Councils of People’s Deputies. Within these zones, the movement of vehicles belonging to the “moderate” and “polluting” categories without an environmental sticker will be restricted. At the same time, social and compensation mechanisms are предусмотрены for residents and workers permanently living or working in these areas. ✨ An environmental sticker is a small step with a big impact. It helps foster environmental awareness, reduce air pollution, and make our cities healthier and more comfortable to live in. 📢 Join us!
