input: Write a function to generate a list of squared values from a given list using list comprehension. The function should take a single argument, which is the list of integers, and return the list of squared values.
  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]
  assert get_squared_values([2, 2, 2])==[4, 4, 4]
  assert get_squared_values([-3, -5, -7])==[9, 25, 49]
output: def get_squared_values(lst):
      return [x**2 for x in lst]
