SQLAlchemy — это штука, которая сильно упрощает работу с базами данных в Python. Она позволяет писать код так, будто ты работаешь с обычными объектами, а не с таблицами. Но если нужно, всегда можно написать чистый SQL-запрос.
Например, вот как легко создать таблицу пользователей и добавить туда запись:
from sqlalchemy import create_engine, Column, Integer, String from sqlalchemy.orm import declarative_base, sessionmaker
Base = declarative_base()
class User(Base): tablename = 'users' id = Column(Integer, primary_key=True) name = Column(String)

Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
Start with a fresh view of investing strategy. The combination of risks and fads this quarter looks to be topping. That means the future is ready to move in.Likely, there will not be a wholesale shift. Company actions will aim to benefit from economic growth, inflationary pressures and a return of market-determined interest rates. In turn, all of that should drive the stock market and investment returns higher.
