Why no output?

Question

def decor(func):
def wrap():
print("============")
func()
print("============")
return wrap

def print_text():
print("Hello world!")

print_text = decor(print_text)
print_text()

Answer 1

Both codes should give the same output. Could you save the former and the latter to different SoloLearn entries and check?

Answer 2

And why this one has output???

@decor
def print_text():
print("Hello world!")

print_text();

Answer 3

it's magic, now they both works, but yesterday the first one didn't

Answer 4

I need help with a similar problem:

text = input()

def uppercase_decorator(func):
def wrapper(t):
#your code goes here
t = t.upper()
func(t)
return wrapper

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

print(display_text(text))
