Decorator function not working

Question

Hi there, can someone help why is my decorator function not working? The output of this is ‘None’, but I expect it to be an uppercase of the Input text.

text = input()

def uppercase_decorator(func):
def wrapper(t):

func(t.upper())

return wrapper

@uppercase_decorator
def display_text(text):
return(text)

print(display_text(text))

Answer 1

Abs Sh is this what u mean? It works now :)

text = input()

def uppercase_decorator(func):
def wrapper(text):

return func(text).upper()
#your code goes here

return wrapper

@uppercase_decorator
def display_text(text):
return(text)

print(display_text(text))

Answer 2

You need to return the value because your argument function 'display_text' is returning a value

Look the following:
...
return func(t.upper())
...

print(display_text(text))
...

Just experiment here:

I hope this solve your problem.

Answer 3

when you call function display_text(text) , it actually calls the wrapper function inside the decorator.

func is the actual display_text function here that you need to print , i.e. print(func(t.upper)).

And since this wrapper doesn't returns anything , using print on it returns None.
