Point objects have x and y attributes (X and Y in C#) attributes. Write a function calculating distance between Point a and Point b. Tests round answers to 6 decimal places.

import math

class Point(object):
    def __init__(self, x=0, y=0):
        self.x = x
        self.y = y
        
    def distance(self, other):
        return math.sqrt(math.pow((other.x - self.x),2) + math.pow((other.y - self.y),2))
