input: Write a python function to calculate the Euclidean distance between two points.
  assert euclidean_distance([2,4], [4,8]) == 4.47213595499958
  assert euclidean_distance([1,1], [4,5]) == 5.0
  assert euclidean_distance([0,0], [3,4]) == 5.0
output: def euclidean_distance(point1, point2):
      return sum((x - y) ** 2 for x, y in zip(point1, point2)) ** 0.5
