where is none coming from

It outputs the input as uppercased but also outputs None https://code.sololearn.com/cv2q87mOHnj5/?ref=app

text = input() def uppercase_decorator(func): def wrapper(t): # you just needed a small change return func(t.upper()) return wrapper @uppercase_decorator def display_text(txt): return txt print(display_text(text))

probablly because within one of those functions you didnt show, theres a call to print. So it prints. But it doesnt return anything so when you call it at the end, you print what is returned, wich is None

Nice! And yeah its a bit weird, i just like to think of returning as grabbing a value and leaving the function. If you have a nested function like your decorator, you can use return to grab a value and exit each function that is nested if you decide to do so!
