Hints

A decorator with arguments is a function that returns a decorator.

That's three levels of functions.

Solution explanation

@repeat(3) first calls repeat(3), then applies the decorator it returns.

Show solution

import functools


def repeat(times):
    def decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kwargs):
            return [func(*args, **kwargs) for _ in range(times)]
        return wrapper
    return decorator


word = input()
n = int(input())


@repeat(n)
def echo(text):
    return text


print(*echo(word))
