Answer 1

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

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

print_text() -> When we call this method, the decorator method will execute first, In this case, decor method: you are passing the print text as a func. when we call the func() -> hello world because you are calling a function. We were wrapping this print text to decor

I go through your code

Answer 2

Why we return wrap and we unable to print the returned wrap and why wrap is used instead of wrap() in return.
And what about the first code.
