Question

I need help coding this with Python.

Create a Point class that consists of an ordered pair (x, y) representing a point's location on the x and y axes. The constructor allow the x and y values to be passed in and should default missing values to 0. You must override the __str__ method to print the point as normal (i.e., "(2, 5)").

Also, create a Line class that consists of a pair of Point objects p and q. A line can be instantiated in one of two ways, as shown below.

somePoint = Point(2, 3)

anotherPoint = Point(4, 8)

someLine = Line(somePoint, anotherPoint)

or...

someLine = Line()

In the second case, the constructor should initialize both points to the origin (0, 0). You must override the __str__method to print the line as follows: "(2, 5)--(4, 7)". Your class must also provide a length method that returns the length of the segment.

Thanks for the question.

Below is the code you will be needing  Let me know if you have any doubts or if you need anything to change.

Thank You !

class Point():

    def __init__(self, x=0, y=0):
        self.x_coordinate = x
        self.y_coordinate = y

    def __str__(self):
        return '({},{})'.format(self.x_coordinate, self.y_coordinate)


class Line():

    def __init__(self, start=Point(), end=Point()):
        self.start = start
        self.end = end

    def __str__(self):
        return '{}-{}'.format(self.start, self.end)

    def length(self):
        square_sum = (self.start.x_coordinate - self.end.x_coordinate) ** 2
        square_sum += (self.start.y_coordinate - self.end.y_coordinate) ** 2
        return square_sum**0.5


def main():
    somePoint = Point(2, 3)
    anotherPoint = Point(4, 8)
    someLine = Line(somePoint,anotherPoint)
    print(someLine)
    print('Lengh: {}'.format(someLine.length()))
main()
