input: Write a function to calculate the perimeter of a circle given its radius.
  assert calculate_circle_perimeter(5) == 31.41592653589793
  assert calculate_circle_perimeter(10) == 62.83185307179586
  assert calculate_circle_perimeter(0) == 0
output: def calculate_circle_perimeter(radius):
      import math
      return 2 * math.pi * radius
