decorators: stack

You're not limited to a single decorator in python. You can apply many if you wish!

To ephesize that you can stack decorators, let's apply two new ones.

import time
import random
from functools import wraps

def print_call1(f):
    @wraps(f)
    def func(*args, **kwargs):
        print(f"print-call 1 args: {args}")
        result = f(*args, **kwargs)
        return result
    return func


def print_call2(f):
    @wraps(f)
    def func(*args, **kwargs):
        print(f"print-call 2 args: {args}")
        result = f(*args, **kwargs)
        return result
    return func

@print_call2
@print_call1
@print_call2
@print_call1
def sleep_random(s):
    """This function sleeps at least for `s` seconds."""
    return time.sleep(s + random.random()/100)

sleep_random(1.5)
