input: Write a python function to calculate the square of each number in a list and return the results.
  assert calculate_squares([2, 4, 8, 16, 32]) == [4, 16, 64, 256, 1024]
  assert calculate_squares([1, 3, 5, 7]) == [1, 9, 25, 49]
  assert calculate_squares([10, 20, 30]) == [100, 400, 900]
output: def calculate_squares(numbers):
      return [number ** 2 for number in numbers]
