I am not abe to understand the working of this code

Question

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

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

decorated = decor(print_text)
decorated()

Answer 1

it is a decorator.

function decor returns reference to its local function wrap().
function wrap() prints "============" then it calls function that was given as argument to decor(func), after that it prints "============" again.

decorated = decor(print_text)
# decorated now refers to decor.wrap() function

decorated()
# call of decor.wrap() function as decorated = decor.wrap

as func argument of decor was print_text,
decor.wrap() do the next:
print("============")
print_text() # as func refers to print_text
print("============")

output will be:
============
Hello world!
============
