What is the need of wrap here??

Question

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

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

print_text = decor(print_text)
print_text()

I have read many explanations but none were satisfactory.

Answer 1

It's just a way to put those lines before and after the text. It would be a lot more readable though if you just took it out though.

Answer 2
