input: Write a python function to create a class Point that can move and calculate distance to another point.
  assert Point(2, 3).distance(Point(5, 7)) == 5.0
  assert Point(1, 1).distance(Point(4, 5)) == 5.0
  assert Point(0, 0).distance(Point(3, 4)) == 5.0
output: import math
  
  class Point:
      def __init__(self, x, y):
          self.x = x
          self.y = y
  
      def move(self, dx, dy):
          self.x += dx
          self.y += dy
  
      def distance(self, other):
          return math.sqrt((self.x - other.x) ** 2 + (self.y - other.y) ** 2)
