A dive into the syntax

Writing a decorator

Although we shouldn’t take “a function that returns a function” as the definition, it is still the simplest form of decorator:

def hello_decorator(func):
    def __new_func(*args, **kwargs):
        # do stuff with `func`, `args` and `kwargs`
        ...

    return __new_func

This is rather straightforward. hello_decorator took a function as its argument, and returned a modified version of it.

@hello_decorator
def my_func():
    pass
