Exercise

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

  • 1

    Add the run_n_times() decorator to print_sum() using decorator syntax so that print_sum() runs 10 times.

  • 2

    Use run_n_times() to create a decorator run_five_times() that will run any function five times.

  • 3

    Here's the prank: use run_n_times() to modify the built-in print() function so that it always prints 20 times!
