0124. Regular Ball Super Ball

Create a class Ball. Ball objects should accept one argument for "ball type" when instantiated.

If no arguments are given, ball objects should instantiate with a "ball type" of "regular."

ball1 = Ball()
ball2 = Ball("super")
ball1.ball_type  #=> "regular"
ball2.ball_type  #=> "super"

Solution:

class Ball(object):
    def __init__(self, type: str = "regular") -> None:
        self._type = type

    @property
    def ball_type(self) -> str:
        return self._type
