I am trying to learn about OOP and inheritance concepts as well as defining a function with an asterisk * before a variable (to unpack its values). When executing the toy code below, I got either an unexpected keyword argument or invalid syntax error.

class A:
    def __init__(self, *position):
        self.max_hp = 100
        self.current_hp = 100
        self.position = position
        
class B(A):
    def __init__(self, max_hp=80, *position):
        super().__init__(*position)
        self.max_hp = max_hp
        self.current_hp = max_hp
        
test = B(position = (20, 30))
print(test, test.max_hp, test.current_hp, test.position)
TypeError: B.__init__() got an unexpected keyword argument 'position'

test = B(*position = (20, 30))
print(test, test.max_hp, test.current_hp, test.position)
test = B(*position = (20, 30))
                   ^
SyntaxError: invalid syntax

Why didn’t the function recognise the argument position? How can I fix it?
