More arguments

So, how do we pass multiple arguments to a method? Let's add a new method that allows us to move a point to an arbitrary position, not just to the origin. We can also include one that accepts another Point object as input and returns the distance between them:

import mathclass Point:    def move(self, x, y):        self.x = x        self.y = y    def reset(self):        self.move(0, 0) def calculate_distance(self, other_point):        return math.sqrt(            (self.x - other_point.x) ** 2            + (self.y - other_point.y) ** 2        )# how to use it:point1 = Point()point2 = Point()point1.reset()point2.move(5, 0)print(point2.calculate_distance(point1))assert point2.calculate_distance(point1) == point1.calculate_distance(    point2)point1.move(3, 4)print(point1.calculate_distance(point2)) ...
