input: Write a function to generate a list of squared values from a given input list using list comprehension. The function should take a list of integers as input and return a list of squared values.
  
  assert get_squared_values([1, 2, 3, 5, 8, 13])==[1, 4, 9, 25, 64, 169]
  assert get_squared_values([-1, 0, 1])==[1, 0, 1]
  assert get_squared_values([2, 4, 6])==[4, 16, 36]
  assert get_squared_values([])==[]
  assert get_squared_values([-3, -2, -1])==[9, 4, 1]
output: def get_squared_values(input_list):
      return [x**2 for x in input_list]
