I don't understand how to pass a callable value into the functions fst and snd. Thanks for your help

A callable object is a first-class citizen, which means it can be used just like any other object, such as an int. Passing a callable object to a function is then done the same way as with any other object:

def my_func():
    print("called")

def consume(obj):
    if callable(obj):
        return obj()
    return obj

# pass an int
consume(42)

# pass a callable object
consume(my_func)

IS there a way I can write a function that returns a value and is callable?

def point(a, b):
    f():
        return a, b
    return f

This is callable but doesn't return a or b

def point(a, b):
        return a, b

This returns a and b but is not callable

I need a function that can do both

That IS callable, and DOES return both a and b.
