Python programming for web development, scripting, and AI/ML.
Use virtual environments (venv) to isolate projects, pip or Poetry for dependency management, and lock files to ensure reproducible builds.
Generators are functions that yield values one at a time, creating memory-efficient iterators without storing all values in memory.
Decorators are functions that modify other functions, enabling reusable patterns like logging, timing, authentication, and caching.
Use a src layout, separate modules by feature/domain, include pyproject.toml for configuration, and follow Python packaging conventions.
Use async/await with asyncio for I/O-bound tasks, run coroutines with asyncio.run, and use await for calling other async functions.
Context managers handle resource setup and cleanup automatically, ensuring resources like files or connections are properly released.
Use SQLAlchemy as an ORM for complex apps, or lighter options like databases library for async. Always use connection pooling in production.
