Python class - decorator

Question

Hi,
I want to display the upper case of a text using a decorator.
I only added the line related to the upper case, other parts of the code are imposed.
I get forr instance :
hello as input
Output:
HELLO
None
How can I get rid of the None?
Thank you.
Code :
text = input()
def uppercase_decorator(func):
def wrapper(text):
#your code goes here
print(text.upper ())
return wrapper
@uppercase_decorator
def display_text(text):
return(text)
print(display_text(text))

Answer 1

text = input()
def uppercase_decorator(func):
def wrapper(text):
#your code goes here
return(text.upper ())
return wrapper
@uppercase_decorator
def display_text(text):
return(text)
print(display_text(text))

Answer 2

return text.upper() instead of printing it in the decorator

Answer 3

Thank you Frogged and Slick. I both understand the exercise and why using return rather than print.thank you

Answer 4

You could also try this out:
text = input()
def uppercase_decorator(func):
def wrapper(text):
#your code goes here
return func(text).upper()
return wrapper
@uppercase_decorator
def display_text(text):
return(text)
print(display_text(text))
