input: Write a function to generate a list of squared values from a given list of integers. The function should use list comprehension to achieve this. If the given list is empty, the function should return an empty list.
  assert get_squared_values([1, 2, 3, 5, 8, 13]) == [1, 4, 9, 25, 64, 169]
  assert get_squared_values([]) == []
output: def get_squared_values(lst):
      return [x**2 for x in lst]
