Instances as Return Values

# Suppose you have a point object and wish to find the midpoint halfway between it and some other target point. 
# We would like to write a method, let’s call it halfway, which takes another Point as a parameter and returns 
# the Point that is halfway between the point and the target point it accepts as input.

class Point:

    def __init__(self, initX, initY):

        self.x = initX
        self.y = initY

    def getX(self):
        return self.x

    def getY(self):
        return self.y

    def distanceFromOrigin(self):
        return ((self.x ** 2) + (self.y ** 2)) ** 0.5

    def __str__(self):
        return "x = {}, y = {}".format(self.x, self.y)

    def halfway(self, target):
        mx = (self.x + target.x)/2
        my = (self.y + target.y)/2
        return Point(mx, my)

print(mid)

# Output:

# x = 4.0, y = 8.0
# 4.0
