The net resut of this function is nothing.  It assigns values, then
they're lost when the function returns.  A function is the wrong way to
deal with these three names.

Same here.

You probably want to have two parameters, player and monster

This function makes no sense to me.  A function should have three
well-defined pieces:  what are its parameters, what does it do, what are
its side-effects, and what does it return.  This function is confusing
on all of those.

What you should want is a class for each type of character. At its
simplest, the class can be a storage place for related named
attributes.

You could make a class Player, which defines attributes called hp,
speed, and attack.  Then later on you can refer to one of those
attributes with  synatax like  james.attack

class Player:
    def __init__(self):
        self.hp = 10
        self.speed = 5
        self.attack = random.randint(0,5)

Now, you create a player by
james = Player()

and the monster by
behemoth = Monster()

and you pass them into the function battle, by

result = battle(james, behemoth)

Inside the function, you'd say  player.attack to see that random value. 
 And monster.speed to see behemoth's speed.
