decorators: inputs

Decorators are functions that make other functions better. It's a bit meta, but they're very powerful. In this series of video's we'll explore them by building our own but also by showing how you typically use them.

Notes

We can also have decorators that accept inputs. This makes for even more expressiveness.

import time 
import random
from functools import wraps

def loggg(show_name=True, show_time=True):
    def stopwatch(f):
        @wraps(f)
        def func(*args, **kwargs):
            tic = time.time()
            result = f(*args, **kwargs)
            result = "call"
            if show_name:
                result = f"{result} {f.__name__}"
            if show_time:
                result = f"{result} time:{time.time() - tic}"
            return result 
        return func
    return stopwatch

@loggg(show_name=False, show_time=True)
def sleep_random(s):
    """This function sleeps at least for `s` seconds."""
    return time.sleep(s + random.random()/100)

sleep_random(1)
