None in the output

Question

text = input()

def uppercase_decorator(func):
def wrapper():

print('###')
func()
print('###')
return wrapper

@uppercase_decorator
def display_text():
print(text.upper())

print(display_text());
Whi is "None" in the output?

Answer 1

because display_text() doesnt return anything and you called print on it. Having None as a return value, it prints the decorater because it was called, and then prints the return value: None

just call the method
