input: Write a python function to calculate the Euclidean distance between two points.
  assert calculate_distance((3, 5), (7, 6)) == 4.123105625617661
  assert calculate_distance((1, 2), (4, 6)) == 5.0
  assert calculate_distance((0, 0), (0, 0)) == 0.0
output: def calculate_distance(point1, point2):
      import math
      return math.sqrt((point1[0] - point2[0]) ** 2 + (point1[1] - point2[1]) ** 2)
