tomevault-io Python Patterns
Idiomatic Python patterns for Python 3.10+.
Type Hints
def process(data: list[str]) -> dict[str, int]:
return {item: len(item) for item in data}
Dataclasses
from dataclasses import dataclass
@dataclass
class User:
name: str
email: str
active: bool = True
Context Managers
with open("file.txt") as f:
content = f.read()
Pytest
import pytest
def test_add():
assert add(2, 3) == 5
@pytest.fixture
def user():
return User(name="test")
Async/Await
async def fetch_data(url: str) -> dict:
async with aiohttp.ClientSession() as session:
async with session.get(url) as response:
return await response.json()
Error Handling
try:
result = risky_operation()
except ValueError as e:
logger.error(f"Invalid value: {e}")
raise
