input: Write a function to generate a list comprehension that computes the squared values of a given list of numbers. The function should take a list as input and return the list comprehension.
  assert get_squared_values([1, 2, 3, 5, 8, 13])==[x*x for x in [1, 2, 3, 5, 8, 13]]
  assert get_squared_values([2, 4, 6, 8])==[x*x for x in [2, 4, 6, 8]]
  assert get_squared_values([])==[x*x for x in []]
  assert get_squared_values([10, 20, 30])==[x*x for x in [10, 20, 30]]
  assert get_squared_values([0])==[x*x for x in [0]]
output: def get_squared_values(numbers):
      return [x*x for x in numbers]
