python

## What I do - Write idiomatic Python - Use type hints effectively - Implement async patterns - Use decorators properly - Handle generators - Use context managers - Write Pythonic code - Optimize Python performance ## When to use me When writing Python code. ## Python Patterns ```python from typing import TypeVar, Generic, Protocol from contextlib import contextmanager import asyncio T = TypeVar('T') # Generators for memory efficiency def process_large_file(filepath: str): with open(filepath) as f: for line in f: yield line.strip() # Context managers @contextmanager def database_transaction(): try: yield commit() except Exception: rollback() raise # Async patterns async def fetch_all(urls: list[str]) -> list[dict]: async with aiohttp.ClientSession() as session: tasks = [fetch(session, url) for url in urls] return await asyncio.gather(*tasks) # Protocol for duck typing class Database(Protocol): async def connect(self): ... async def query(self, sql: str): ... # Type hints from dataclasses import dataclass @dataclass(frozen=True) class User: id: int name: str email: str ```
