Функция asyncio.wait() это еще один способ вызвать множество асинхронных задач. Она работает в нескольких режимах. 1. Самый простой - ждем завершения всех задач async def main(): tasks = [asyncio.create_task(do_it(i)) for i in range(10)] done, pending = await asyncio.wait( tasks, return_when=asyncio.ALL_COMPLETED ) for task in done: try: print(task.result()) except Exception as e: print(e) Очень похоже на gather, но работает не так. ▫️возвращает не результаты, а два сета с объектами Task у которых можно забрать результат через task.result() если они в списке done ▫️не гарантирует порядок результатов так как оба объекта это set ▫️не выбрасывает исключение когда оно появляется, а сохраняет его в Task. Исключение появится когда попробуете забрать резултьтат. 2. Ждем завершения первой задачи, даже если там ошибка. async def main(): tasks = [asyncio.create_task(do_it(i)) for i in range(3)] done, pending = await asyncio.wait( tasks, return_when=asyncio.FIRST_COMPLETED ) # в done может быть несколько задач! for task in done: try: print(task.result()) except Exception as e: print(f"Fail: {e}") # Оставшиеся задачи в pending, как правило, нужно отменить, иначе они будут продолжать работать for task in pending: task.cancel() В сете done будут таски которые успели завершится, причем как успешно так и нет. 3. До первой ошибки. Тоже самое, но с аргументом FIRST_EXCEPTION done, pending = await asyncio.wait( tasks, return_when=asyncio.FIRST_EXCEPTION ) Функция завершается как только первая задача упадет с ошибкой. Учтите, что в любом случае done вы можете обранужить несколько задач, как с ошибками так и успешные. ↗️ Полный листинг примеров здесь #async

#disease🤢 #Glanders: A Zoonotic Disease Affecting Equines and Humans 🟢1. Cause of Disease: Glanders is a contagious and often fatal disease caused by the bacterium Burkholderia mallei. This bacterium primarily affects equines (horses, donkeys, mules) but can also infect other animals and humans. 🟢2. Ways of Conflict and Disease Transmission: • Direct Contact: The most common route of transmission is through direct contact with infected animals, such as through bodily fluids (nasal discharge, saliva, urine, milk), or contaminated equipment. • Inhalation: Inhaling contaminated dust or aerosols can lead to infection. • Ingestion: Consuming contaminated food or water can also cause infection. 🟢3. Disease Symptoms: Glanders can manifest in both acute and chronic forms, with symptoms varying depending on the severity and location of the infection. Acute Form: • High Fever: Sudden onset of high fever. • Nasal Discharge: Thick, purulent nasal discharge that often has a foul odor. • Coughing: Severe coughing with potential respiratory distress. • Skin Lesions: Nodules and ulcers on the skin, often on the head, neck, and limbs. • General Weakness: Loss of appetite, lethargy, and muscle weakness. Chronic Form: • Chronic Nasal Discharge: Persistent nasal discharge, often with a more localized involvement of the nasal passages. • Nodules: Subcutaneous nodules, especially around the head and neck. • Joint Pain: Lameness and swelling in joints. • Lung Lesions: Pneumonia and respiratory complications. 🟢4. Disease Diagnosis Methods: • Bacteriological Culture: Samples from nasal discharge, skin lesions, or blood can be cultured to identify the Burkholderia mallei bacterium. • Serological Tests: Tests to detect antibodies against the bacterium. • Polymerase Chain Reaction (PCR): A molecular test that detects specific DNA sequences of Burkholderia mallei. 🟢5. Disease Treatment and Appropriate Drugs: • Antibiotics: Treatment typically involves long-term administration of specific antibiotics like tetracyclines or aminoglycosides. • Anti-inflammatory Medications: To manage inflammation and pain. • Supportive Care: Hydration, nutrition, and symptomatic treatment. Glanders is often difficult to treat, and long-term follow-up is necessary to prevent relapses. 🟢6. Disease Prevention: • Quarantine: Strict quarantine measures for infected animals and potential contact animals are essential. • Vaccination: A vaccine for horses is available in some countries, offering limited protection. • Biosecurity: Implementing strict hygiene practices to prevent the spread of the bacterium, including disinfecting equipment and minimizing direct contact with potentially infected animals. • Early Detection: Promptly identifying and isolating animals exhibiting signs of Glanders is crucial for preventing further spread. 🟢7. Quarantine & Human Involvement: • Quarantine: Quarantine of infected animals and animals that may have been in contact is crucial to prevent further transmission. • Human Involvement: Glanders is a zoonotic disease, meaning it can be transmitted to humans. The most common route of infection in humans is through contact with infected animals or their bodily fluids. Human symptoms are similar to those seen in horses, and treatment often involves antibiotics. 🟢8. Immunity and Recovery: • Immunity: Recovery from Glanders does not guarantee immunity, and reinfection is possible. • Recovery: The disease can be fatal, even with treatment. Recovery can be prolonged, and long-term complications are possible. 🔴Important Note: Glanders is a highly contagious and potentially fatal disease. It's crucial to consult with a veterinarian immediately if you suspect your horse or another animal may be infected. https://t.me/vets_hub
