Decorator function not working

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))

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))

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: https://code.sololearn.com/cqeQuldcDAEk/?ref=app I hope this solve your problem.

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.
