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)

Last Friday, the National One Health Technical Committee (NOHTC) brought together key stakeholders across human, animal, and environmental health to:
✅ Review progress on previous action points
✅ Share updates on ongoing programmes and current outbreaks
✅ Align strategies to strengthen Nigeria’s health security through coordinated, multisectoral action
Together, we’re advancing a resilient, data-driven OneHealth system for prevention, preparedness, and response.

🚨 Public Health Advisory: Ebola Virus Disease (EVD)
The Nigeria Centre for Disease Control and Prevention (NCDC) has released a public health Advisory following the announcement of an Ebola Outbreak in DR Congo.
Though no case has been reported in Nigeria, NCDC is closely monitoring the situation.
Key Preventive Measures:
▪️Wash hands frequently with soap & running water
▪️Avoid contact with sick individuals showing symptoms like fever, vomiting, diarrhoea & bleeding
▪️Avoid bushmeat and ensure all animal products are well-cooked
▪️Healthcare workers: maintain high IPC standards & use PPE 🧑⚕️
Read the full advisory 🔗https://ncdc.gov.ng/themes/common/docs/protocols/369_1757166366.pdf
If you or anyone you know (with recent travel to affected areas) experiences symptoms, call 📞 6232 or your State Ministry of Health hotline immediately.
Together, we can prevent the spread and protect Nigeria. 🇳🇬

🚨 PUBLIC HEALTH ADVISORY 🚨
The Nigeria Centre for Disease Control and Prevention (NCDC) has announced that Nigeria currently has no confirmed case of Ebola Virus Disease (EVD), following the ongoing outbreak in the Democratic Republic of the Congo and a reported imported case in Uganda.
🦠 Ebola Virus Disease is a severe viral illness transmitted through direct contact with infected bodily fluids or contaminated materials.
Common symptoms include:
✅Fever
✅Headache
✅Weakness
✅Muscle pain
✅Vomiting
✅Diarrhoea
✅severe cases, unexplained bleeding.
The NCDC is actively strengthening surveillance, laboratory readiness, infection prevention, and public awareness efforts across the country. Nigerians are advised to remain calm, maintain good hand hygiene, avoid misinformation, and report unusual illnesses promptly.
Stay informed through official public health channels only. Together, we can strengthen preparedness and protect public health.
#Ebola#PublicHealth#NCDCNigeria#HealthSecurity
#Ebola is caused by the Ebolavirus — a group of viruses with several species, including Zaire, Sudan, Bundibugyo, Taï Forest, and Reston ebolavirus (which affects animals but not humans).
Knowing the cause helps us strengthen prevention and response efforts. 💪🏾
Stay Safe, Stay Protected!
#EbolaAwareness#HealthSecurity#NCDCNigeria
