Writing Python Decorators

Melissa Nuño9 years ago

So Easy, a Caveman Could Do It

A decorator is merely a function (or callable object) that accepts a function and returns a function. A very basic decorator can be defined like any other function:

def my_decorator(func):
    return func

Functionally, the following two snippets are the same:

def my_func():
def my_func():
my_func = my_decorator(my_func)

Notice that the function call is implied in the first case. The portion after the @ character is evaluated when the function is defined, and just has to resolve to a callable object. There is no magic involved here.
