Использование Pydantic сегодня стало нормой, и это правильно. Но иногда на ревью вижу, что используют его не всегда корректно. Например, метод BaseModel.model_dump() по умолчанию не преобразует стандартные типы, такие как datetime, UUID или Decimal, в простой сериализуемый для JSON вид. Тогда пишут кастмоный сериализатор для этих типов чтобы функция json.dump() не падала с ошибкой. import uuid from datetime import datetime from decimal import Decimal from uuid import UUID from pydantic import BaseModel class MyModel(BaseModel): id: UUID date: datetime value: Decimal obj = MyModel( id=uuid.uuid4(), date=datetime.now(), value='1.23' ) print(obj.model_dump()) # не подходит для json.dump # { # 'id': UUID('4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1'), # 'date': datetime.datetime(2025, 12, 12, 12, 12, 12, 111111), # 'value': Decimal('1.23') # } # добавляем свой кастомный сериализатор json.dumps(obj.model_dump(), cls=MySerializer) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2025-12-12T12:12:12.111111', # 'value': '1.23' # } В данном случае класс MySerializer обрабатывает datetime, UUID и Decimal. Например так: class MySerializer(json.JSONEncoder): def default(self, o): if isinstance(o, Decimal): return str(o) elif isinstance(o, datetime): return o.isoformat() elif isinstance(o, UUID): return str(o) return super().default(o) Специально для тех, кто всё еще так делает - в этом нет необходимости! Pydantic может это сделать сам, просто нужно добавить параметр mode="json". json.dumps(obj.model_dump(mode="json")) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2012-12-12T12:12:12.111111', # 'value': '1.23' # } #pydantic#libs

🎯 Cohesive Markers in IELTS Writing: “However”, “On the other hand”, “Nevertheless”, “On the contrary” Many IELTS candidates use these interchangeably — but each has a different nuance and function. Let’s break it down 👇 🔹 However → introduces contrast or opposition to the previous idea. ✅ Example: The internet has made communication faster. However, it has also reduced face-to-face interaction. 🧠 Use it when contrasting two aspects of the same topic. 🔹 On the other hand → introduces the other side of an argument or comparison. ✅ Example: Some believe online classes are more flexible. On the other hand, others argue they reduce motivation. 🧠 Use it to show two perspectives, not just contrast. 🔹 Nevertheless → means “despite what was said before”. It softens the contradiction. ✅ Example: The task was challenging. Nevertheless, the students completed it successfully. 🧠 Use it when you acknowledge difficulty but show a positive outcome. 🔹 On the contrary → used to refute or correct a previous statement. ✅ Example: Some claim young people are lazy. On the contrary, many work hard while studying. 🧠 Use it when directly disagreeing or correcting a wrong view. 💡 Summary Tip: ❌ Don’t use them randomly. ✅ Choose based on logical relation: Contrast → however Opposite view → on the other hand Concession → nevertheless Correction → on the contrary ✍️ Accurate cohesive markers = higher coherence & cohesion score in IELTS Writing! #IELTSWriting#Cohesion#AcademicEnglish#LinkingWords

To be herded into doing something Meaning (short): to be forced or strongly pressured into doing something without real choice. توضیح فارسی: عبارت to be herded into doing something یعنی فرد یا گروهی به‌صورت اجباری یا تحت فشار شدید و بدون اختیار واقعی به انجام کاری سوق داده می‌شوند؛ معمولاً با حس کنترل شدن، مثل راندن گله. این نشان می‌دهد که در شرایطی که پوشش رسانه‌ای شدید و جهت‌دار درباره یک اتهام وجود دارد، ممکن است افکار عمومی بدون فرصت بررسی مستقل و انتقادی به سمت پذیرش یک روایت خاص سوق داده شوند؛ یعنی عملاً «گله‌وار» به یک نتیجه هدایت شوند، نه اینکه آگاهانه آن را انتخاب کنند. #Vocabulary #AcademicEnglish #CriticalThinking #MediaLiteracy #DiscourseAnalysis #PowerOfLanguage #EnglishLearning #AdvancedEnglish
