input: Write a python function to calculate Euclidean distance between two points.
  assert euclidean_distance([[1, 2], [4, 6]]) == 5.0
  assert euclidean_distance([[2, 3], [5, 7]]) == 5.0
  assert euclidean_distance([[0, 0], [0, 0]]) == 0.0
output: def euclidean_distance(points):
      import math
      point1, point2 = points
      return math.sqrt((point1[0] - point2[0])**2 + (point1[1] - point2[1])**2)
