func is an argument given to the function identity_decorator().

The expression func() means "call the function assigned to the variable func."

The decorator is taking another function as an argument, and returning a new function (defined as wrapper) which executes the given function func when it is run.

Here is some information about decorators.

I was wondering the same! You can see how it works with the follow example:

def make_pretty(func): def inner(): print("I got decorated") func() return inner def ordinary(): print("I am ordinary") pretty = make_pretty(ordinary) pretty() Output I got decorated I am ordinary 

Now when you remove the func() and you try to rerun it:

def make_pretty(func): def inner(): print("I got decorated") return inner def ordinary(): print("I am ordinary") pretty = make_pretty(ordinary) pretty() Output I got decorated 

You see the the decorated function was not called. Please have a look here
