Run_n_times()
In the video exercise, I showed you an example of a decorator that takes an argument: run_n_times(). The code for that decorator is repeated below to remind you how it works. Practice different ways of applying the decorator to the function print_sum(). Then I'll show you a funny prank you can play on your co-workers.
def run_n_times(n):
"""Define and return a decorator"""
def decorator(func):
def wrapper(*args, **kwargs):
for i in range(n):
func(*args, **kwargs)
return wrapper
return decorator
