def decor(func): # We create a decorating function that takes another function as a parameter def wrap(): # Nested function that wraps around the function we chose in our parameter print('-'*40) # Creates 40 dashes on top of our function func() # Calls the function we used in our parameter print('-'*40) # Creates 40 dashes below our function return wrap() # Prints out what is in our wrap function @decor # Calls our decor function def text(): # The function that gets called by decor print('decorate me!') # defines text to decorate print(text) # Prints our text function that calls decor

It didn't answer my question, everything I understand before what you explained here. Without, wrap function in decor, which is not called. So, how it can be functioning!

wrap gets assigned to function 'text' using @decor in the above example. So, when we call text, wrap gets called actually.
