A decorator that profiles a method call and logs the profiling result

I want to create a decorator that profiles a method and logs the result. How can this be done?

Solution

  • The decorator would look something like:

    import time
import logging

def profile(func):
    def wrap(*args, **kwargs):
        started_at = time.time()
        result = func(*args, **kwargs)
        logging.info(time.time() - started_at)
        return result

    return wrap

@profile
def foo():
    pass

    Anyway, if you want to do some serious profiling I would suggest you use the profile or cProfile packages.
