Question

This is my code:

def execute(f, *args):
    f(args)

I sometimes want to pass no function f to execute, so I want f to default to the empty function.

Answer 1

I don’t understand very well what are you trying to do
But would something like this work for you?

def execute(func=None, *args, **kwargs):
    if func:
        func(*args, **kwargs)

You can also add an else statement to do whatever you like.
