input: Write a function to generate a list of squared values using list comprehension, given a list of integers. The function should return the list of squared values.
  
  def get_squared_values(input_list):
      return [x*x for x in input_list]
  
  assert get_squared_values([1, 2, 3, 5, 8, 13]) == [1, 4, 9, 25, 64, 169]
  assert get_squared_values([]) == []
  assert get_squared_values([0, -1, -2]) == [0, 1, 4]
output: def get_squared_values(input_list):
      return [x*x for x in input_list]
