input: Write a python function to calculate the square root of a given number and return the result.
  assert calculate_square_root(81.0) == 9.0
  assert calculate_square_root(16.0) == 4.0
  assert calculate_square_root(0.0) == 0.0
output: import math
  
  def calculate_square_root(number):
      return math.sqrt(number)
