It works now thank you! i didn't realize that you could use another return

Answer 3

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))

Answer 4

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

Answer 5

I don't understand lmao, is it like it prints something but doesn't return anything?

Answer 6

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!
