I am trying to learn about python function decorator. So far I am following a tutorial. I have writing the same code. but still I am getting the error that

NameError: name 'new_decorator' is not defined

. What could be the reason for that. Thanks a lot.

What I have tried:

@new_decorator
def func_needs_decorator():
    print("This function is in need of a Decorator")


def new_decorator(func):

    def wrap_func():
        print("Code would be here, before executing the func")

        func()

        print("Code here will execute after the func()")

    return wrap_func

func_needs_decorator()

Python is interpreted language and thus each type needs to be defined before it can be used in the program ahead. Try defining the new_decorator above your func_needs_decorator function.

Python

def new_decorator(func):
    def wrap_func():
        print("Code would be here, before executing the func")
        func()
        print("Code here will execute after the func()")
    return wrap_func

@new_decorator
def func_needs_decorator():
    print("This function is in need of a Decorator")


func_needs_decorator()
