Quick & dirty python timer for copy/paste perf. Handy for quick measurements of functions with the decorator or blocks with the context manager

t.py

from contextlib import contextmanager
from functools import wraps
from time import perf_counter


@contextmanager
def t(name: str):
    start = perf_counter()
    yield
    print(f'TIMER {name}: {perf_counter() - start}')


def td(f):
    @wraps(f)
    def wrapper(*args, **kwargs):
        with t(f'{f.__name__}'):
            return f(*args, **kwargs)
    return wrapper
