Question

Using Python 3:

Create a point p1 of coordinates (0; 0) and un point p2 of coordinates (1; 2). Print out the coordinates of
the two points on the same line, by calling toString on the two points. Print the
result of applying the method equals on point p1, using p2 as argument. Set the x
coordinate of p2 equal to the x coordinate of p1, using the methods setX and getX.
Set the y coordinate of p2 equal to the y coordinate of p1, using the method setY
and getY. Print again the result of applying the method equals on point p1, using
p2 as argument. Increment by 1 the x coordinate of p2, using the methods setX and
getX . Print again the result of applying the method equals on point p1, using p2
as argument.

Answer 1

class Point:
    def __init__(self,x,y):
        if(not isinstance(x,int) or not isinstance(y,int)):
            raise ValueError("Invalid coordinate")
        self.x = x
        self.y = y

    def getX(self):
        return self.x

    def getY(self):
        return self.y

    def setX(self, X):
        self.x = X

    def setY(self, Y):
        self.y = Y

    def Print(self):
        print(self.x,self.y)

def main():
    try:
        q = Point(3, 4)
        q.Print()
        q.setX(5)
        q.setY(7)
        q.Print()
    except ValueError as ex:
        print(ex)

main()
