Hints

A decorator takes a function and returns a new function.

@functools.wraps keeps the original name and docstring.

Solution explanation

@shout above a def is shorthand for greet = shout(greet).

Show solution

import functools


def shout(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        return func(*args, **kwargs).upper()
    return wrapper


@shout
def greet(name):
    return f"hello, {name}"


print(greet(input()))
print(greet.__name__)

Output
