# Point and LineSegment

You are required to develop a

`Point`

class with two attributes: `x`

and `y`

, representing the x-coordinate and y-coordinate of a point on a 2D plane. The Point class should have a method named `distance_from_origin`

that calculates and returns the distance from the point to the origin (0,0).Subsequently, create a

`LineSegment`

class with two private attributes: `p1`

and `p2`

, each being an instance of the Point class, representing the endpoints of the line segment. The `LineSegment`

class should have a method named `length`

that calculates and returns the length of the line segment.Input | Output |

`first = Point(3, 4); second = Point(6, 8); seg = LineSegment(first, second); print(second.distance_from_origin()); print(seg.length())` | 10
